I need help identifying that gun.
My Cashmore is one originally sold in Victoria Australia.
There are lots of Cashmores in Australia & I paid AU $250 for it.
The barrels are 30" 1 1/4 oz proof & in the best condition I have seen, after looking at very many & more expensive. No dents, no rust pits internal or external & it locks up tight. It is cased with a cleaning kit & I think that the original owner must have been a bit fastidious about cleaning the bore after use.
