Ebay turned up a couple of tool box doors, with one set of knob / spring / nuts. I believe that one is for TY250. But I'll get them bothe prepared with the frame, and see which one fits or looks best. Then I'll sell the other one as they do make decent money - up to £40+.
I've also bought from Ebay, two sets of foot pegs / foot peg brackets, and made a decent set out of the three lots I then had.
So, along with the repaired frame, I'll be sending the below to the frame finishers to do all in one batch.
