OK thanks for the information.
So,mid 1860's at the latest seems to be the consensus?
I must admit that was my pick just looking at it but the smaller hammers threw me.
Any opinion on the barrel length? they seem a bit short but appear original.
I don't have any info on where it came from as yet but will enquire,but as it never had any German proof marks applied post 1891 as I believe was normal practise maybe its been out of that country since that time.
I have discovered it has a cracked bridle on one lock and one of the hammer spurs needs attention any recommendations to repairing it?

Cheers,
