Taunton Penny Post - No.2 RH Handstamp ?

The partial entire shown below was a recent acquisition.  It has a 1d black cancelled with a blurred Maltese Cross, a Taunton dated Penny post handstamp for 15th February 1841 and an unboxed "No.2" handstamp.

Unfortunately the partial entire does not include the address that it was written from, however the filing note says "Mr Hancock to Mr Row".  It is likely that it was from Mr Hancock who was a Solicitor at Wiveliscombe.

Any information on where the "No.2" Receiving House handstamp came from gratefully received !
