View attachment 696946 Although, there's no doubt that this bike was put together from parts of all ages, and that I do agree, that the straight back Cyclock configuration was a 1936 first year introduction.
That type of lock arrangement was still being used at least up until 1940.
I've been working on a 1939 Schwinn DX that came equipped with the Cyclock, and to my surprise, it's a 1936 configuration.
Unusual for sure, but another case where Schwinn was using up old stock on the popularly priced budget models.
What seemed strange to me, was that they omitted the truss rod tangs for the DX line.
I would think, that any of the old stock 36 Cyclock forks would've already had the tangs attached. So, if that was the case, then they had to go through another step in the process to remove the tangs, to equip the 39 DX with a Cyclock fork.
Unusual? I don't know.
But, interesting for sure.
