I agree George. Hence why I wrote "possibly"...phonogfp wrote:
I think it's premature to even consider the "P-word" until the serial number is known. I do expect this machine is early production since the only other metal-cased lever-wind Berliner with a brake is numbered in the 80s (eighties). If so, it begs the question of why the brake on this model was discontinued during its production.

I too find it strange the lever brake appears to have been eliminated during this models short run; even though the run was very small in numbers.
However, we also find the later wood case version ratchet winds with both brake and sans brake and arm rest. Although, a completely different brake design. I wonder why..??. Another great Berliner mystery.
In the case of the metal cased model, it's far more complicated then not screwing parts onto the wood case. They had to retool for a new case without the raised/contoured area for the brake. Seems like additional cost in order to eliminate the brake...

Then, we find a lever brake design used slightly later again.
