Hello

As I had awared, there are many different mounts and body designs to this famous lens. I got 2 here. On the left is M42 and on the right is unknown, I used M39-M42 ring on it but too big, Therefore I grind it down and hammer the M39-M42 ring into it. To bad it cannot reached infinity. As for the M42 ones, I got problem removing the front most glass despite, knocking, sucking, digging, it just wont bugle and comes out ! what shall I do ?
