Some time ago I acquired a Zenit 3M made by KMZ, but overlooked that the pressure plate was lacking.
Meanwhile two soviet pressure plates made their way to my stuff:
-) one from a Zorki (I guess) that would fit the 3M with little grinding at the latch openings, but that would ly inbetween the lateral guide rails of the Zenit.
-) one that would fit directly, but being very filimsy with the back opened and likely then to fall out. It would sit on the lateral guide rails. Thus forming a channel for the film.
The mere fact that the Zenit 3M got these rails and moreover got them grinded, make me think that it was intended to yield a film channel, as in installing the 2nd pressure plate.
Can someone who got a 3M confirm this?
(At looking laterally into the inside at halfway closing the back it is possibke to see whether the plate rests inbetween or on the lateral rails.)
