About 7 or 8 years ago, I bought one of the early Pakistan/India sourced tanks for a Norton Commando. Rough as a cob and sides were poor match in contour. Welds were very "iffy" looking so I made a rubber stopper with a Schrader valve in it, stopped up the fuel tap holes, put about 5psi in it and put it in my little ones backyard pool. DOZENS of pinhole leaks! Just as troublesome, the mounting for the flip up Cee and Ess fuel cap was a horrible fit and wouldn't allow the cap to open properly. LOTS of filler and a TON of work to get it ready for paint, but eventually was acceptable. Around the same time, Michigan Norton Owners restored a Commando to raffle off for charity and also bought one of these tanks. Unfortunately, painter didn't test fit cap before doing a beautiful metalflake blue paint job and it was ruined in efforts to fix lousy cap mounting, so had to be painted twice. I am TOLD that aftermarket, third world sourced tanks are now of much higher quality, but I have no personal experience with these later ones. I'd advise a very close inspection for fit, finish, leaks, threads, etc, before paint.
