I had something very interesting occur yesterday morning: an ebayer contacted me, asking about the following pipe, advertised as a 1941-43 shape 44 Dunhill (previous owner's claim). He said that he was curious if the repair band could be removed, how solid the repair was, and what stamping was underneath the band. I bought the pipe 4-5 years ago for less than $80 and have smoked it consistently, so I figured I'd take a look, and if I destroyed it, not a big deal.
I pushed at the band with my fingernails and, all of a sudden, it flew off, leaving a chunk of briar in my lap, and a smaller chunk on the couch. I was kind of horrified. The pieces did not fit back together well - residue all over the connection areas (probably a 1950's or earlier repair), and the small piece was something that the original repairer had carved to plug a hole where briar was missing. After scrubbing the stamping area and the connection areas of the pieces, and soaking it all in alcohol, I was able to discern the faint impression of the 'D' in England, and a '3', making this a 1923. The big chunk fit much better after that. The '3' was just at the bottom of the large cracked off piece, so became a glue victim.
Long story short, I worked all day on it, and re-stained it to Dunhill plum. The stem was not original and did not fit well after the repair, so I had to work on that some as well. Final pipe shown below. I'm really grateful that the ebayer spurred me to do this and I'll get back to smoking this pipe, enjoying it even
