400NitroExpress:
The Clabrough and Johnstone is a BP proofed hamer gun. Mid range engraving on the side locks, trigger guard and fences.
It has a Birmingham address on the barrel rib, the proofs are BV , Birmingham.
Nice steel barrels. Wood is pretty standard straight grain walnut. Overall, nicely finished gun.
Little use. Bright barrels that measure as if no polish or freshing has been done. 2 1/2 chambers.
My boxlock I. Hollis is a I. Hollis, London, but, after reviewing again, it has the typical Birmingham Nitro proofs of Birmingham. My Hammer Hollis is a Brimingham address on barrel and Birmingham proofs. This one with a bit of use, but solid and shootable.
Maybe one or both are WC Scott built guns!?
