As a descendant of Samuel Smallwood I was interested by your post. I'm starting to take an interest in family records. As an engineer of sorts, I'm rather fascinated by Sam Smallwood and his rather beautifully made guns.
My Dad was MD of GH Smallwood and Co untill it folded in the economic climate of the 1980s.

If you'd like to swap notes on Sam Smallwoood and his activities I'd be interested.

BTW I know nothing about guns!
