I think it's actually a replacement from a model with a smaller mortise... it shouldn't go in quite that far to the shoulder but I've seen a lot like that it must have happened a lot!
or it's been jammed in there really far.. that's possible too!
Now smoking Ken Byron Ventures Burley Morning Pipe in a 1998 smooth medium bend Peterson Limerick 69 with a nickel band with a tapered black vulcanite p-lip stem. Been very busy today.
Now smoking Watch City Rouxgaroux in a 2003 smooth three quarter bend Rinaldo Fiammata Odissea Titania 02 Silver Line 3 Straight Grain egg with a black acrylic tapered stem. Sorting out photos for an interview I granted for a book.
A minute or two away from smoking year 1983 Condor RR in a small 1982 three quarter bend unbranded meer with a smiling turbaned Turk's head and a yellow acrylic tapered stem.
Tabac-Manil Semois medium cut in a Bari smooth bent billiard my late wife's aunt gave me one Christmas about 40 years ago. This is the Belgium burley variant in a now discontinued Danish brand of pipe, both classics.
