Here is again a Leningrad.This is a newer model than the previous one, you might call a "type 2". It is distinguished externally by four screws on the front instead of two.Several improvements have been made:-New-molding of the shutter block (the previous used the one of Zorki 4) allowing the addition of a plate bearing covers, to improve the light sealing (the first model fogged the films while changing lens).-New grooved metal film pressure plate, the previous was made of glass.-The rewind button can now be disengaged, no longer turns during the film advance.
Good surprise at disassembly: virtually no traces of wear, this camera (from 1962) is almost new!some screws are loosened, the rangefinder wanders.The dtretcher of one curtain is cut and the rubber of that curtain is cracked. To replace.The other curtain is good.Attempts for setting the rangefinder distorted alignment of the small window, to review.
Replacing the curtain.
Disassembling and degreasing gears.
Reassembling the shutter.There is an additional piece compared to the older model: a plate bearing light tight baffles.
This part in position.
It takes several successive disassemblies and reassemblies to ensure proper operation (the spring cocking device is in the top cover, impossible to properly test the shutter without putting it back).
Revision of the rangefinder, complicated setup with the 3 screws (now blocked with pink nail polish) and three against-screws for having the "small image" straight and at proper height.
Reassembling completed.
