I'm curious to know the date of this bike. It doesn't have a Sturmey Archer rear hub, instead it has a 3spd hub with Hercules A type O made in England on it, and no date. It has rod brakes, when did they stop using those? I didn't see a serial number on it, I checked the left side of the seat post with no luck. It's all original, paint,tires and all, well maybe not the seat. Thanks, Dean
