Hi all, I bought this over the weekend at a local gun show but aside from knowing what it is, I have no idea as to age or what country it was used by. I suspect it English in manufacture, it has the name W. Deane on it and I am familiar with the English gun manufacturer Deane, Adams and Deane so I purchased it, thinking that maybe at one time the company made scientific instruments as well a sporting guns.

The protractor is used to determine the caliber of cannons and shot but there is a host of other scales and mathematical functions on the scales and I hope one of our European brothers can add some insights to my recent purchase.

I think these are reproduced for the US Civil War reinactor crowd but I'm pretty sure this is an old protractor.

Regards,

Greg
