Hi! Thank you for your replies and info.
The only mark on the tang are i. Hall and those on the scales.
I agree that i was meant to have one of them.
The one i bid on and lost sold for £87, the one i bought yesterday only cost £25 so was a bargain and a lucky great find.
So if i am correct in reading your post, it could have been made between 1795-1830 by J.Hall?
