Here are two 1981 hallmarked Peterson Mark Twain pipes. Both are normal issue (not the numbered ones).
The main difference is the stamps - I've never seen another Mark Twain, from any year, with the large stamp that is perpendicular to the band stamping. Another difference is the ferrule size - slightly taller, but thinner cap walls (where the tenon inserts). Final difference is the molded ridge that runs up the side of the oddball pipe. It was even more pronounced when the pipe arrived, but the feel of it was very obnoxious so I took off enough to where you can't feel it, but preserved the fact that it was there.
The stummel is pretty much identical, as is the stem (both have the embossed 'P').
I'm curious what other Peterson collectors think about this - the odd one arrived with the normal red box and papers.
