On Arm: "New Departure Pat No 20891 1898 21038 1900"
I've tried to find this hub on this thread, this site, and parts catalogues and can't find it. It doesn't have the tiny teeth on the brake arm and disc with three holes (parts A10 and A9 respectively). Instead it has a brake arm with three holes. It came on a bike I acquired recently which is in very original condition, and laced into a Lobdell steel lined wood rim with the patent date July 19, 1910. At first I thought this was an older version but the NOS 1908 hub posted by Pelletman in post #5 has the little teeth. The bike is a Hyslop, "manufactured" in Toronto sometime in the teens using rims and other parts sourced from the US. Would it have been cheaper to manufacture the hub without the teeth? Perhaps it was a cheaper version of the Model A used to compete in export markets? I was not able to find those patent numbers on the 'Net so I don't know if they are US patents or Canadian. Another possible explanation is that New Departure had the patent for the little teeth in the US but someone else held a similar patent in Canada.

I was hoping dating the hub could help me date the bike, but no luck so far. If anyone has any information, other theories, or pictures, please post. If someone can find those patent numbers that would be great too! Attached are photos of the hub and the bike it came on. The hub looks a bit gold in colour and I think a previous owner coated it with varnish or shellac.

Bought this wood wheel set (back shown). It is a 40 hole (front 32, I think) laced to the remainder of a new Departure shell.
What bike would this have been laced to? The only one I have seen with this configuration.

Have a look at post 352 and 355. I had the bike in 355 and sold it last spring. British bike, probably Humber from what I could find. It is now in Toronto.
