Trivelox Model B derailleur, introduced in 1937.

I had never heard of Trivelox until I read about it on BF. This website is always educational! Do you have the full Trivelox setup, with the sliding cog hub?

No, that's all I have. This is a pretty conventional derailleur; it moves the chain sideways, the way all modern derailleurs do. The original setup for this derailleur included a freehub (not a freewheel) and an indexed quadrant shifter on the top tube.

So, I guess Berto didn't know about the Trivelox, eh?
