[Leica] One dot, two dot???

[Frank.Dernie at btinternet.com (Frank Dernie)]

One of the weak points of the original M3 was the rewind spindle broke. 
The earliest models had a slot filled with red paint in the top of the 
spindle, which could be viewed as a film transport confirmation as it 
rotated. Later cameras has a red pain filled offset dot and eventually 
a larger strengthened spindle with 2 red dots.
