Can anyone help me?  I am attempting to trace markings found on a small (9.25
inch) bronze signal cannon from a late 1600's Spanish shipwreck. Please suggest
any books, magazines, publications or papers that have such listings,
ie...photos of stampings along with a description of foundry, years produced,
nationality, ect...  I have 2 scanned photos of the cannon. If you think you
might be able to help me directly, please e-mail me and I will forward them.
 
Also, can anyone offer any suggestions as to the use of such a small piece on
board?
 
Please forgive cross postings.
 
Thank you,
 
Jim Michon
