Hi in my role as co-editor of Post-Medieval archaeology I am editing a 
paper about c15-C18 armament foundry in Dubrovnik. The excavator's have 
produced half of a round iron shot c. 10cms with  a hollow  section only 
it looks too tube like and small for a  normal incendiary shell. 
Thoughts that have crossed my mind include a failed attempt at making a 
bar shot though it could have been intended as a gate ornament?? Royal 
Armouries weren't much help. If anyone would like to see a jpeg email 
me(with the excavator's permission)  and I'll post by return.
