Well spotted , Daryl!

The Cogswell and Harrison is, apart from the presence of ejectors and a slightly more typical shaping of the front of the Westley Richards style top lever, a near twin to mine.

I wish mine still had Damascus barrels, but then if it had it would no doubt have cost me more than £55.

I see that the gun you mention is marked C & H on the tubes where the barrel maker’s stamps would appear. Cogswell and Harrison were manufacturers, and unusually for London makers built boxlocks in house.

It seems likely that this was one of their own making.

It is very close in date to mine, and raises a moderately strong possibility that they built mine for E. M. Reilly.
