Thanks David. I might see what I can fashion from this file - appreciate the measurements too. Champion!!
No I do not have the instructions....the M2 arrived alone - well of course it had the usual Leica spirit crammed in the box too
Be great if you could dig out the original instructions as I am working from internet commentary, reason, and healthy dose of trail and error. Suffice it to say that I have sacrificed my share of leader to the camera's innards ..OUCH!
