This is a very interesting mark. Thomas Hannam is recorded as having been in
partnership with Ebenezer Coker, a partnership that dissolved in 1760.
Grimwade suggests that the mark TH over RM has some doubt over it as
recorded in Jackson’s. Thomas Hannam is also recorded as being in
partnership with John Crouch, making salvers and waiters. Their mark also
appears on candle-sticks. The TH RM partnership is recorded as them being
Goldsmiths. John Crouch and Thomas Hannam, (in that order), are recorded as
plate-workers, which ties in with them making salvers and waiters.
