I bought an A10 tank a couple of years ago, round badge type. It came with a fuel cap but no badges or taps. Overall I was happy with it. Looked good fitted well but had rust inside which I treated with Tapox, probably worth doing even without the rust given the problems caused by ethanol in modern fuels. I bought it on e-bay from seller AAKASSHUKLA, based in New Delhi which I assume must have a humid climate!, (still advertises), paid £200 delivered to my door. Add the cost of Tapox and a little work I thought it still worth it.
