I haven't spoken to Steve no but I think my originals are too damaged and too faded to use as templates.
World Cycle Decals and bicycledecalsltd on ebay both do the Mk1 and Mk2 but the Mk2 set they have is spot on except it is missing the yellow flash around the BSA on the down tube, so I'm not sure if they’re set is wrong or there's yet another variant about, can't say I've seen a Mk2 in the flesh without the yellow flash though
