A cannonball ... a pommel ... or what ?

[christek]

Hello Fernando,

A difficult job identifying this ball,

If it is indeed a cannon ball, it could possibly be part of a grapeshot canister, but most of these that I have seen are of a more circular shape, as in the pic shown.

I am unsure of what the nick or mark may indicate, however;

I wonder if it could possibly be a ball for a naval swivel gun, the diameter of the ball is almost perfect size as swivel guns are among the smallest types of cannon, typically measuring less than 1 m (3 ft) in length and with a bore diameter of up to 3.5 cm (1¼ in); which appears to be the correct size of your artefact.

Just a thought

Kind regards,
Chris
