Summilux 50 Type 1 serialnumber

[Erik van Straten]

The scalloped focusing knurl (SKF) was made up until 1960 in the 1,757,000-1,760,000 batch, which also included the last lenses recorded at the factory as being black paint. It’s a very interesting production run.

It is remarkable that Leitz called this "black paint", because the aluminium parts of the lens are chemically blackend, not painted. Only the brass parts are painted.

Leitz called it schwarz lackiert, which some of it is. These things don’t always make sense.
