Heres a picture of an original (Large British collection)
It has the italic "ALL" and two "reg'd trade mark" (below both the Gargoyle and Mobiloil) and it also differs in the area of the handlebar.
Originals seem to be rectangular and repros square.
Compare original to the one on ebay mentioned in earlier post above.
