This is a big-bore learning curve for me. Here is an non-serial-numbered 4 bore Reilly (no SN means Reilly marketed it but likely didn't make it though it has London proof marks) on Guntrader.UK - 36" barrel, extra-full choke, 12 lbs:

Comments:
-- Trigger guard tang that apes a pistol grip.
-- Original center-fire
-- Weight indicates it is an original shotgun
-- 36" barrel length would seem to tend to 1870's.
-- Original London Proofs 1855-1875 for a 6 bore.
-- Full choked barrel (post 1875) but no "not for ball"? (Might the 6 bore barrel in itself = "full choke?"
-- Reproofed after 1989 as a 4 bore. (Might "23.4" be 6 bore in mm?)
-- Chamber 101.4 mm (4 inches)
-- £6,900 - a lot of money

So is it a 4 bore or a 6 bore, or a 4 bore with a 6 bore barrel in the 19th century, and why a full choke with no "not for ball"? So many mysteries and such a great place to have them explained.
