These are one of the oddball newer pieces that has been discussed, it is a 41' date code Hemi 12 that has been embossed with hand done script letters and numbers rather than the newest machine embossing of the era. The N, G, S, R, and 1, and 2's are all quite distinctly hand done on these and is an unlisted variant in any guide. As far as I have seen, this hand engraving was done only on 41' date coded pieces which are harder to find compared to the 1950 mould. Mint cond and will definately add an unusual embossed clear piece to your pony collection. Email me if you want closeups of the lettering. $5 + $4.50 shipping in USA/Canada.
