I recall Hilary posting a 1946 Gillott on ebay with these decals. I wonder if he might have some information to share. Ken Denny listed a 1948 or 1949 a couple of months ago with script style lettering. I was under the impression that the block style lettering came later than these bikes as well. Certainly not sure though.
