I'll see about acquiring a 44M-4 and possibly a 44M-6 for research. From the research I've done prior to purchasing my set of 44m's I would guess there is little difference. The spring controlling the aperture mechanism should be safe to remove as long as you put it back later. If you can't access it from the rear of the lens it may be necessary to do so from the front. You may even have to remove the 'guts' from the lens housing. If I can get my hands on a model 44M-4 I'll give it a go. I’ve never had the privilege of dismantling a 44M-4.

I had removed the backplate and aperture ring, then removed 3 screws holding on the aperture control mechanism, but wasn't able to see how the remove this plate to continue disassembly, since there seems to be a spring connected underneath the plate that controls the aperture open/close mechanism, so I bailed (didn't want to ruin my $10 find!). thanks!
