The mount was Taken from an Old Soviet KIEV Camera, as well as the Lenses. I wanted to keep the Mount Part of the Camera in as much of an untouched state as possible, and only removed a little material where it was unavoidable, otherwise the Overall adapter could have been a little bit smaller.
Overally a very nice Kit of vintage lenses, which gives a really high Quality Vintage Look (those Lenses are Russian copies of early German Leitz/ Leica Optics, but usualy WAY Cheaper to get, bought all of this for like 30 to 40€, dont quite remember anymore, however the Mount will ofc also take Leitz brand lenses...). And those Lenses are SHARP. The 50mm has quite flat color rendition (which i like), but gains some Contrast when stopped down a bit. The 35mm has surprising amount of contrast considering its age, just a outstanding lens. The 135mm is a very solid lens also in terms of image Quality. Seems to be at least as sharp as the 35mm, as far as i was able to test it, and also has a bit of a softer and flater color rendition than the usual modern lenses.

Hacked together a Adapter for Sony-E-Mount when i got those, and went to a local Camera store to try them on an α7R III just for Kicks, and even on that sensor fully Zoomed in, it was still as sharp as can be (except for the 50mm wide open untill like f/5.6 or /8, where it also gets as sharp as the sensor can even capture... Hardly noticeable on lower resolution Sensors). Truly impressive for lenses of that age.

Nice and compact In Size, but sadly not the fastest apperture Lenses ever (35/2.8 50/2 135/4), but still reasonable for outdoor Lighting, where you would stop down anyways to get at least some depth of field.
