According to the a copy of Powell's ledger I finally ran across, I have serial number 5889(9 lbs) which looks like it went to Mess. Sch??, Hartley & Graham, "One our patent action with stub dams. barrels 30 inches 12 bore, our patented strikers + rebounding locks, old bolt, ..." There's No. 4865, 6041, 5887, 5889, 5890, 6053 & 6054 on this copy. Mine's in rough shape as some A$$ cut the tubes back to about 25 inches. I inquired to Peter about a new set of tubes and his quote was around 9k pounds.

Kind Regards,

Raimey
