This is a query for the most wise and experienced. I have an M3 and finally noticed that the baseplate thread is 3/8 inch and not the "standard" 1/4 inch. Now I have to fool around with reducers. However, it makes me wonder as my local camera store owner who has seen literally thousands of Leica M3 claims never a 3/8 baseplate thread. Even thought it was a prototype. Many Leica III's have 3/8 inch base plate threads. I could probably raise a fuss with the person who sold to me, but not really interested. Is it an affront to my Leica manhood that I have this oddball?
