Planistigmat Posted February 9, 2012 Share #1 Posted February 9, 2012 Advertisement (gone after registration) Hello together I like scewmount Leicas. I met strange shutter speed dial in Leica III. Camera is from 1934 (by number) but on bottom plate is engraved "closed" and "open". Lens number tells it is from 1946 and is coated. After number of lens - Elmar 3.5 / 5 cm - there is asterisk "*". I guess camera went back to factory in 1946, bottom plate was changed and lens was renovated with new number and "*". Till now everything seems to be clear for me. But camera has strange shutter speed dial. There is one tooth on it and 3 smaller tooths upper. Could you tell me why shutter speed dial is not typical ? I think it can be related to flash synch but I don't know which way. Below you can see few photos of the shutter speed dial http://i1238.photobucket.com/albums/ff500/Planistigmat/le2.jpg http://i1238.photobucket.com/albums/ff500/Planistigmat/le3.jpg Link to post Share on other sites More sharing options...

earleygallery Posted February 9, 2012 Share #2 Posted February 9, 2012 Very odd! It looks like somone has taken an angle grinder to the dial. I suspect it's some kind of DIY bodge, for whatever reason. Link to post Share on other sites More sharing options...
philipus Posted February 9, 2012 Share #3 Posted February 9, 2012 I saw such a dial on a II or maybe it was a III at Red Dot in September. It's been sold now, however. In an email they told me the dial had been replaced without specifying where it came from. Link to post Share on other sites More sharing options...
earleygallery Posted February 9, 2012 Share #4 Posted February 9, 2012 It could be some kind of adaption for a flash unit - the 'lobes' might trigger a switch or circuit on some kind of flashbulb holder as the shutter is fired..... Link to post Share on other sites More sharing options...
hoferat Posted February 9, 2012 Share #5 Posted February 9, 2012 its a geiss synchro-contact to trigger the flash Link to post Share on other sites More sharing options...
lars_bergquist Posted February 9, 2012 Share #6 Posted February 9, 2012 In the early 1950's non-synched Leica cameras could use the Vacu external synchroniser, for the CAVOO flash unit. The synchroniser was screwed on the shutter-release guard thread and fitted over the shutter dial. A synch cord went to the CAVOO. There were six different lobed dials, to fit different cameras, named CAVOO-A to CAVOO-F. A Leica III from 1934 should take a CAVOO-A. Thank God I never had to use one of those Rube Goldberg contraptions. The old man from the Age of Flash Powder Link to post Share on other sites More sharing options...

jc_braconi Posted February 9, 2012 Share #8 Posted February 9, 2012 I have a IIIb which is equipped with this camed shutter dial to work with the Vacu (like a ruptor for dispatching to the sparks plug on an engine) Welcome, dear visitor!

TomB_tx Posted February 9, 2012 Share #9 Posted February 9, 2012 My aunt's 1948 IIIc came to me with one of the synch cams pressed on the normal shutter speed dial. Its larger diameter actually helped grasp and adjust the dial. Too bad the flash unit was gone by the time the camera came to me... Link to post Share on other sites More sharing options...
pico Posted February 10, 2012 Share #10 Posted February 10, 2012 Thank God I never had to use one of those Rube Goldberg contraptions. And thanks to him that Canon had a very nice bulb flash for the Leica at the same time. Reliable, used medium and large bulbs. A wonder unto itself. Need pictures of it? .

lars_bergquist Posted February 10, 2012 Share #11 Posted February 10, 2012 Lars, wasn't it CMVOO the specific code of the "cammed" speed dial ? Anyway... Welcome to the forum, Planistigmat !!! You see... HERE YOU CAN FIND ANSWERS !!! CMVOO seems to have been the dial supplied with the COOIF synchroniser for electronic flashes. When you think that the Kine-Exakta had internal synchronisation already in 1936, the knots that Leitz tied themselves into to avoid this solution until 1953 are truly Gordian.
