J.W. Benson 'Bank' watch, 11J, 1922
The case has the same numeric serial number as the movement so the date is pretty certain.
Some Benson 'Bank' movements and its derivatives after c 1901 have a serial number prefixed with a letter. About 12% of the 59 Benson 'Bank' watches I have seen have this numbering system but the percentage would be somewhat higher if only watches after 1900 were considered.

Unusually for Benson those movements with an Alphabetic prefix to the serial number often have the same serial number on the case as on the movement but without the prefix which makes the dating certain (unless the watches were re-cased by the maker).
The silver case, hallmarked for J.W. Benson 1922 serial No 4381.

So together with the lack of correlation between the letter and dates it appears the letter represented something else.
