A bit off-topic in that not a gun at all, but here's a couple of pics of my next favorite Peter Orr collectable:
a silver pocket watch from the days of the Raj.

I also have a large solid silver trophy cup engraved in swami style hall-marked P. Orr & Sons and presented to an unknown recipient by the Southern India Rifle Association, some other hall-marked silver items too.

Love this stuff!
