I've inherited this James Dixon and Sons powder flask. Its graduated for 4/8, 5/8 and 6/8 dram. The powder loads are the same as a Colt pistol but the adapter is longer and narrower than the pics I've seen. What gun might the flask be used with? A small rifle maybe? I'm also trying to work out its value as some go on ebay for £30 but others are much more.
Seem to have lost my googlefu on this!
Thanks,
Rob
