Here are the dimensions for the 140 from 1951. Reuben Charatan was known to be quite exact of the lengths of his catalogue shapes. Now I have seen the original box, I am fairly certain that this piece is from the late 1950s. I think Jon Guss may have some more info relating to when Charatan acquired their various Charatan shops namely Panton Street, Jermyn Street, Grosvenor Street and Whitcomb Street. Charatan used to include these shops on the box. I think Barry first started his apprenticeship with Reuben in Vine Street. I will ask him next time I speak when the Minories factory was in use and possibly approximate dates that the other shops opened (and closed). This is another way of dating the pipe.
Yes Jensen, I am sure that Henley was the name of the shop that the pipe was supplied to. The aspects I am not sure about are the mouthpiece, the small flaws I see on the bowl of this Deluxe (unusual) and the character of the Charatan's make London, England stamp.
