Hi Ian, paint stripper was the first product used (didn't mention it earlier on...woops), not keen on the steel wool as when I say it is "very very fragile", I mean exactly that. The script 'Willys Overland' would more than likely disappear with very little effort and the remainder is almost lost already, it can only be read when tilted to catch the light. The only really defined writing is the stamped in serial number 'CJ3A 17122'.
I'll bring them over next time I come around, i.e. when the TJ's front locker has been rebuilt.
Before (but after the paint stripper and some degreaser)
After (tilted in the light to get best effect)
