You may well be right Steve and you've seen a ton of guns. However, as an observation with a database of 600 extant Reillys, of which 100+ are rifles, I can say I have never seen a Reilly center-break rifle with 30" barrels. And most are 26" or 28." Example from rifles close to the above serial number:

A .577 OBSOLETE CALIBRE DOUBLE BARRELLED HAMMER RIFLE BY REILLY & CO., 26inch sighted blacked barrels engraved with the manufacturer's details on the sighting rib, border engraved signed sidelocks, border engraved rotary underlever action, half stocked with chequered fore-end and wrist, border engraved steel mounts, serial no. 17261, contained in a later case with a selection of accessories.
