I found this Hemi 154 to be a bit more unusual than average. The N in HEMINGRAY is a solid raised glass prism instead of a letter. I would suspect that this is the result of a worn mould making this error. The N on the rear skirt is sharp and perfect, so it has to be something with the front half of the mould itself. I had one of these where the H was a prism and that sold FAST....so if you like the 154's a bit different, I offer another one that will fill another hole in the error pieces. Insulator is bright Hemi blue and only has 1 flaked RDP.This one was also personally pulled down by myself last week from a local area, so you know where it's hailed from. $4 + $7.50 shipping.
