Cast Iron or Bronze

[enrada]

I would like to find out if anybody knows what kind of cannons the HMS Challenger 1826 would have had on board.
It shows that it was a 28 gun 6th rate ship.
Gun deck 20 X 32 pounders
QD 6 X 18 pounders
FC 2 X 9 pounders
What I really want to know is how many were iron and how many were bronze. Prefer not to have speculation or guesses.

All iron.

Thank you. Wreck site is close to where I am working on another site. I'll run a mag over it.

This article might be relevant to the Challenger. It gives some visibility into how the many overlapping and competing agencies in the Chilean government deal with treasure hunting. Different treasure, different island, same country’s bureaucracy.
