Advertisement Posted October 25, 2009 Posted October 25, 2009 Hi jc_braconi, Take a look here A strange item. I'm sure you'll find what you were looking for!
giordano Posted October 26, 2009 Share #2 Posted October 26, 2009 Can you decipher the engraving on top of the item, or do you have another picture that shows it more clearly? Link to post Share on other sites More sharing options...
luigi bertolotti Posted October 26, 2009 Share #3 Posted October 26, 2009 Is the knob BLOCKED by the device ? Link to post Share on other sites More sharing options...
earleygallery Posted October 26, 2009 Share #4 Posted October 26, 2009 Very strange, obviously some home made device. It would appear to stop the winder knob from being used but also means that the rewind lever cant sit in its proper position. I would suggest that its a device to make multiple exposures, i.e. hold the film in place, disengage the gears and cock the shutter with shutter dial? I can't see any other reason to 'lock' the winder, although from experience on my lllf if the rewind lever isn't fully in it's home position the shutter malfunctions - it trips but doesn't always open.

bill Posted October 26, 2009 Share #6 Posted October 26, 2009 It's not one of those cord "rapid winders" is it? You know, like starting a motor-boat engine??? Regards, Bill Link to post Share on other sites More sharing options...

Anyway, your explanation has a sense; btw I notice that the "accessory" required, apparently, to make a small hole (threaded ?) into othe top plate... not a fine operation to do...

earleygallery Posted October 26, 2009 Share #9 Posted October 26, 2009 I don't see anything threaded into the top plate? If it was a rapid winder it almost certainly wouldn't work because the rewind lever can't sit in its proper position. Curious........... Link to post Share on other sites More sharing options...

I meant this...looks that sort of ratchet is kept firm with a sort of "pin" someway fixed onto the plate... but who knows... Welcome, dear visitor!

earleygallery Posted October 26, 2009 Share #11 Posted October 26, 2009 Luigi, that is a 'stop' for the rewind lever (present on my lllf's) although I'm not sure if all the earlier cameras had it. The device has been made to lock onto the pin for some reason and I can only think that it is to prevent the film being wound on. It definately looks like a crude home made thing!

Yes they have. and please note that the collar is all around the winding knob. Link to post Share on other sites More sharing options...

giordano Posted October 28, 2009 Share #17 Posted October 28, 2009 And indeed they have the pin... My IIIg (879xxx) does not have it. On reflection I think that this is indeed a double-exposure device. With the A-R lever in the midway position shown the shutter is uncoupled from the film advance mechanism but the shutter release works normally. In this state you can cock the shutter by turning the speed dial and thus make multiple exposures. The device on top of the wind knob (a) locks the film transport to avoid accidental movement and ( marks the position required for the A-R lever. In addition I'll wager that it's spring-loaded so you can pull it up to disengage the locking tag from the pin and then advance the film ready for another batch of multiple exposures.

jc_braconi Posted January 7, 2010 Author Share #18 Posted January 7, 2010 Seeking for an another item in the James Lager book Vol III Leica Accessories p51, I found this one : the Rapido that matches verywell with the one that we discussed about and in fact even if the original picts are no so good we can see that something was engraved on the top.

UliWer Posted January 7, 2010 Share #19 Posted January 7, 2010 Lager's translation of the engraving "D.R.G.M" is not correct. "Gesellschafts" "Muster" would mean "Society" "Patent", making no sense. D.R.G.M is short for "Deutsches Reichs-Gebrauchsmuster" meaning "Utility Patent in the German Reich". Link to post Share on other sites More sharing options...
earleygallery Posted January 7, 2010 Share #20 Posted January 7, 2010 That's the fellow! Curious device, sounds dangerous - risk of chopping off a finger on some cheese-cutter type wire! I wonder how much faster it was in practice? I can wind my lllf pretty quickly by holding the knob and turning the camera, but I'm not usually in that much of a hurry!
