from the ebay listing for this bicycle:
Jack Taylor Tricycle, Kendrick type, While Taylor frames and machines are all highly collectable, this one is UNIQUE: as far as I can find out this was the only one made! I understand that this was possibly made as a prototype, just post-WWII, in response to government contracts for vehicles for disabled servicemen. Now restored to original parts with 2 replacement rims (32/32/40), and a couple of new inner tubes. Sturmey Archer 3 speed hub with integral brake & 1 caliper rear brake.
