Again this is from my uncles accumulation:

The one on the left has the numbers 121968 around the middle of the barrel and MADE in CANADA PAT. 1937 on the barrel closest to the arm.

The middle one has MADE IN CANADA 40 NEW HERCULES BRAKE PAT NO. 10638 PATS PENDING on the barrel on the outside of the spoke holes

The one on the right appears to be unmarked.

I was wondering if I could get and info on these at all?

Thanks for all your help.
