Just putting the finishing touches to a 2001ish T1 barcode myself, so looking forward to seeing your pics.
Have managed to get the head-tube sticker sorted but finding it tricky to get the barcode sticker, only place
I can find them is on the actual T1 site.
Was going to be running a 13-36 gearing set-up but after getting all the parts realised this combo would not
work with the position of the brakes (more or less touching)
so it's back to the drawing board.
