I'm trying to restore vintage bicycle I happen to own. I came to the stage of pulling cranks off and it apperas that I can't find the appriopriate tool to do that. Could anyone advice me on this? I attached some photos of the thread in the crank.
As some pointed out in comments there is separate thread in the bottom bracket axle. It's a square taper bottom bracket and the crank is bolted onto it just like with modern square taper BBs. In other words there is a thread in the axle and a separate, bigger one in the crank. The problem is a thread gauge. I thought I could find appriopriate puller online but I failed.
I've taken a picture of bicycle itself, and also I managed to scrape black paint from a little plate riveted to the headtube uncovering name of the bicycle manufacturer. Apart from that, and the facts Pashley is a British company, I don't know anything about bicycle's origin.
