Posting for a friend, who has a friend that's trying to figure out what this thing is. Any thoughts? For scale, the second pic shows a bit of her thumb.
A couple comments from her:
The front: "CD Whereat Ironmonger" or possibly GD
The back: "Dolphin St. & Castle St Bristol "
"the round disk on the front slides and there is a "tension" pin ( looks like) inside...."
"looks like a "key" goes in the round disk which slides left and right....then it releases...if I understand correctly"
My friend did track down a GD Whereat in Bristol who worked as an ironmonger in the 1850's, but that doesn't help much with figuring out what it is. Also he had no luck with a Google image search.
I'm guessing a scale of some sort, but that doesn't explain the key mechanism or the overly long stem on top.
