[QUOTE=cs1;7560425]Thanks for the reply. I'm surprised that there's so few replies on the subject. Considering how important decals are to the vintage restorer.QUOTE]

I agree. To the restorer, or anyone who wants make their bike look better, then accurately reproducing decals is very important. Unfortunately most decals are hard to get off without messing them up. Vinyl decals are easier than some because you can heat them up with a hair dryer to soften the underlying adhesive and then (very carefully) try to pull them off intact. Water transfer decals will almost always self destruct when you try to take them off, so thats a bummer.

I'm no expert in this field, but I would think the best one can do is take many multiple close-up macro shots of the originals with a good digital camera, relative to the tube size with all measurements to try and have them accurately reproduced by someone.

It seems the only thing you can do.
