The Smithsonian used to sell a replica in their catalog -- I'd check with them.

We have in our collection a small sundial cannon, called either a time gun, a noon gun or a cannon dial. It was developed in the early 1800's and is a horizontal sun dial usually on marble or stone, with a miniature cannon and two brackets that support a burning lens. The lens is calibrated for the noon sun and when it hits the lens, the cannon goes off. Does anybody have any information on these objects, know of a publication about this or anything else that would help us to properly identify what we have and to date it. Thanks for your help!
