1935 1936 1937 1938 Cabriolet top iron latch

[Karl Wescott]

I am working on making the 1937 cabriolet top iron latch. I received a request from a person with a 1935 cabriolet which has a similar latch. The parts books I have are sketchy and confusing as to what was used.



Questions...
1935 handle should be chrome? 1936-38 painted? When did the bump that is 2/3rds down the handle appear? Are the two versions interchangeable? Are there more versions?


Photos are of the 1935, the 1937, and my work in progress 3D CAD model.
