Perry Coaster Brake Hub

In response to my query a few days ago, a kind reader (rb, of A Balanced View) has helped me identify my rear hub as a Perry & Co. coaster hub (i.e. back-pedaling brake). Apparently, the big arm (the brake actuator) coming off the left side of the hub and clamped to the frame should have been my first clue (you learn something new every day). Here's a diagram of the hub, with all the bits identified. I'm thrilled that I have a coaster brake--I haven't had one since I was a wee lad.
