I cannot see anything on the tang behind the trigger guard, is is a bit corroded though. I'm not 100% sure what the forearm is, I haven't heard that term before. There is a number on the rib; R 97. The top of the barrel is engraved 'Reilly' and what looks to be '& Co London'. 13 is stamped on the underside of the barrel, with the proof marks (gauge/bore size?).
