I bought another BSA pump last week at a local auto jumble, this time I was sure I had the right one, but when I got home I tried it under the tank its an inch too long. And now looking at it again I have noticed it has one of those strange swallow tailed broad arrows on the side which I had seen before but wasn't completely convinced about. It also has a maker "Bailey's Super Pump Made in England".
Could it be for a pre war BSA V twin or is it simply for a BSA Military Bicycle?
