The guy did not want to sell it, it seems.
I recently bought a Field, London gun, SxS hammers and damascus bls, from a dealer in Ontario. Advertised as bores bright, good overall condition. I tested it with normal loads, 2 1/2", roll crimp, 2 3/4 drams 1F and 1 1/8ox. shot.
Missed 2 birds out of 20 shots on the quail-walk at Hefley and got second place. Nice gun and damn glad I bought it, just for the quail walk at rendezvous. It was under $350.00. Most of the colour case is still there. A plain gun, some engraving.
Sometimes you just have to take a chance with the old stuff.
Oh yes - VERY bright bores, well maintained and not used much.
