Industar to M3 problem

I bought a Industar-22 collapsible to sit on my M3, making a compact everyday package. Does not work.
The focusing tab/infinity lock position on the lens makes it impossible to fit the lens on the camera, it hits the bayonet lock before fully in place. Does not matter whether the bay adapter is first set on camera or first on lens.
I can not find any workaround so the lens has to sit on a Zorki or Bessa-L.

Is it the same story with the LTM Elmar 3,5? I guess it´s not but then I guessed the same for the Industar.

Per, when fitted the focusing lever on the I-22 is at about 9 o'clock facing the front of the camera. On the Leica lenses it is at about 7 o'clock. If you look at the bayonet adaptor it has a cutout on the outer edge to clear the infinity lock on Leitz 50mm lenses. You can make the Industar fit by removing the little spring loaded plunger that locks the lens at infinity. Only problem is that the screw (on mine at least) requires a pin wrench to remove it.
 
I had the same problem with my I-22 and my Canon 7 - the latch would hang up on the .95 lenses external bayonet. So I did just simply remove the locking pin.

It takes about 3 hands to take off the spring loaded pin :) but it can be done. I used two pliers and was able to hold the back still while turning the front until I could finish loosening it by hand. There are three pieces - the back, the front and a small sprint - that you'll want to put into a zip lock and save for if you ever wish to sell the lens.

The very similar Fed lens (I've heard it described as an I-10) and my 1936 Elmar, both fit onto my M3 without difficulty. The Fed lens has less of an extension behind the infinity lock button than the I-22, I guess.

I did this with my I-22 and it now works fine on my M6 classic. I am a bit scared about collapsing the lens into the body, though. (So I put on a rubber band just in case.) Can I collapse it totally?

I'm not sure. What I would try is putting the shutter on T, opening the back (there is that little door on the M's IIRC?) and watch while pushing it all the way back slowly to see if there is any hang up on anything. That's what I did to verify that the I-22 and J-12 both would work just fine on my Canon 7.

Let us know,

This explains the I-22 I bought on e-Bay that came without the locking plunger. I wondered what ever possessed someone to go to the trouble to remove it and then place it back on a beater Zorki-1.
