    luigi bertolotti got a reaction from Anbaric in Collapsible LTM Summicrons   
    What has been made on your lens is of course undefinible... maybe a badly made disassemble/reassemble... or maybe they hav mixed parts coming from different lenses : for example.... I have two Summicrons LTM - rather distant as s/n (920.xxx and 1043.xxx) - as you can verify, the top lens group is easily unscrewable, leaving "open" the diaphragn mechanism : well, if I exchange the two groups, the Summicron becomes grossly out of focus... probably the real focal length of my two items is different, and the curavtures of front and back groups don't match each other.

    My only left field recent purchase was a Rolleiflex 3003. This basically was the camera that broke Franke & Heidecke. It was an absurdly over-ambitious exercise, where between the 35mm system cameras 2000/3000 series and the medium format 66/6000 series there were some 40 new lenses designed to be built by Zeiss, Rollei, Kirin and Minolta plus dozens of dedicated accessories. They refitted the old Voigtlander factory in Braunschweig and the Rollei factory in Singapore to build the new lenses. The cameras were all made in Germany. The 3003 was the same price as a Hasselblad XPAN. It is fairly unergonomic to use and was obviously designed more as a studio camera than hand held. 
    I put in a bid of €400 for the camera, two film backs, a battery pack, 50mm/f1.7 Zeiss lens, 35mm/f2.8 Rollei/Minolta and 28-105mm Rollei/Kirin, not expecting to win but I did. I then bought a spare battery pack, which arrived with yet another film back. Sadly the diaphragm is stuck wide open on the otherwise excellent 28-105mm lens (a Zeiss design). My local repairer had a look at it but could not even work out how to open the lens up. Newton Ellis up in Liverpool think they may be able to repair it and I must get round to sending it up there.

    Me too time to time think of getting an Alpa (even made a tentative at an auction, conscious that I had 99% chance to be outbid... 🙄 base price was under the normal evaluation for its Macro Switar), but I fear that in case, knowing my passion for glass, I'd subsequently start to chase for lenses, with unpredictable GAS costs... 😁
    Contarex, several years ago, was the only SLR I used... a noisy heavy device with spectacular optics and a meter which drained battery like an engine for a radio controlled model car... .

    ... and about conversion to IIIa (could be that it would fit more into another topic, "old Leica converted.....").
    There is no technical  restriction why III cannot be converted to IIIa. Besides speed dial another three parts, hidden under the top plate, are different: speed disc (note smaller hole for 1/1000, this is why at 1/1000 speed dial sits higher), speed selector and latch for the 2nd curtain. Latch has an additional bolt, this is for 1/1000.

    Well... by chance in my professional life I have seen other examples of similar behavior by manufacturers (not longtime ago, in the agri mechanical sector...where you also have standard items that can have a very long lifecycle, even passing through different owners) ... it's all about a serious approach to the task of "manufacturer guarantees to be able to maintain any item he has built". To elaborate :
    - Suppose they had engraved onto a new serial taken from the current batches, (but probably, in that year, there was not even a "current batch" of Leica III... but let's suppose it would be) 
    - One day, years later, they receive for maintenance camera xxx.xxx : they say "OK, it was batch xx of year yy... bodies were made THIS way (docs in house)
    - They disassembly the camera ---> it results not made THIS way... confusion, loss of time, and in the case that, for commercial policy, a standard CLA on a standard item has a standard price... there is a problem
    - But if the camera is clearly identified thanks to a not standard s/n, they know from the start they must work differently... they can understand and (probably) reconstruct the story behind... and, for instance, warn the customer or dealer that "this is a non standard maintenance task... quotation follows" (or "maintenance to be carried on time&materials basis")

    Me too think that this "Germany" engraving is probably very significant about timing : an original rework made postwar; hipotesis : a very worn II sent for tentative overhaul/upgrade, which resulted impossible/not worth, and the customer got this camera, assembled out of line (*) with the original s/n + asterisk to indicate that, even if probably delivered with warranty, this was not a standard manufactured item.
    Nice item 😎... a good an intersting find for a passionate of Barnacks
    (*) assembly made in the repair department, with some spares too, maybe... if so, I wouldn't be surprised that Leica , today, can't say anything about the history of this item : keeping track of pruduction is one thing, keeping track of repairs all another one.

    Hi,
    First of all, thank you very much @nf3996 and @Pyrogallol for sharing that information.
    Regarding the conversion from III to IIIa it seems that the policy changed with time. Interesting to note that the policy regarding black/chrome finish, didn't changed with years.
    I'm quite sure that many of you already know this list but just in case (1952-1953 conversion prices courtesy of Jim Lager).
    Best wishes,
    Augusto

    There are a lot of items in the book by Lars, which are not to be seen. So, that 'mausoleum ' must be quite full. I quite liked the displays in the museum as education is a very central role for most museums these days. The problem for Leica AG is that while there are a few us who are interested in the really rare items and prototypes, the vast majority of people coming in the door only have a general grasp on photography and the history of Leitz/Leica.
    Another item in the 'mausoleum', which is almost as rare as the Ur-Leica itself, is the 7.5cm Leitz Elmar for the Kochmann Korelle K, of which only one copy seems to survive. I managed to obtain one of those cameras and then I separately found the tiny 3.5 cm Leitz Elmar with its own aperture control. This is also a very rare item which is different to the LTM 3.5cm and also the Leitz lenses on Nagel and other Compur mount cameras which have the aperture in the shutter. The Kochmann has a Compur shutter, but the aperture is in the lens rather than the shutter. A photo of the Leitz Elmar lens for the Kochmann is below beside the 3.5cm Elmar for LTM. I hope to be able to suggest to Leica that a Collectors's Club might be set up for people like ourselves, who could, in turn, provide assistance to the company. There is a lot of knowledge on this forum which the company could use, particularly as it is also a seller and auctioneer of vintage items.

    Super interesting find 😎. I leave ponderings about to real experts: my rough idea : assembled in Canada - tops from Wetzlar (spares ? leftovers ?) The indication fo 2 last batches of 100 is reported also here, for what is worth : https://www.cameraquest.com/ltmnum.htm
    Can you post some other detail, like bottom, also with cover removed ?

    My Zeiss rangefinder cameras are few, I, II, IIIa.   But the Contarex, pulled me in with its complexity. I have the chrome models( Bullseye, Special, Professional, Electronic), but never a black one. Several motor drive systems and heavy zoom lenses. Now, if I could just find a reasonably prices repairman to keep all those finicky shutters going!

    I think that "spy camera" , in our photographic language, stands for "a camera to take photos without the photographer is noticed to do"...  this can be indeed an item use by spies... but to take copies of documents : Leitz made a lot of such equipments... in the '60s, which can be the times of this item, Reprovit is the most known example. Would be interesting to see what is the lens fit onto... it looks to have a standard diaphragm (aperture 5,6).... maybe even a focusing helicoid.... the frame counter goes to very high numbers, which makes to think to small/vertical format (18x24 ?) - logical choice indeed for document pages. Not so ckear how is performed the shutter operation... maybe there is a leaf shutter into the lens (is there a "30" engraved onto ?) to keep opened for focusing through the upper hole before starting the reproduction process.
    Very interesting gear, anyway: was it simply displayed, or offered for sale ?
    (the calculator / adding machine at right is Brunsviga-style...  : https://www.ebay.it/itm/284126359595?hash=item422740302b:g:-3IAAOSwh-Rf57Hj One of my old uncles was incredibly quick to operate his one... as a surveyor, used it + a ruler till the '80s...)
