I will now talk about screw mount Leica black paint and let us focus on Leica II and III this time.
Let us now talk about strap lugs of black paint cameras.
Leica M3 and M2 are considered to be full black paint cameras in general with almost all parts in black paint (of course early batch of buddha ear M3 is probably the authentic full black paint camera, with serial number starting from 959, or all earlier black batches - I will cover that later). Therefore, M3 and M2's strap lug are black paint on brass, and when the paint comes off (brassing), it will show a golden brass colour underneath.
Anyone here interested in Leica Black Paint camera? Why all Leica collectors at some point of time are so obsessed with Black Paint Leica? They look like defected paint, they are not durable like chrome, they are not consistent and all look different.
