Brought home scrap, and the cloth eating moth

So why are the cannons between the two countries different that can be seen on a magnetometer??

Yea, Spanish used I think copper to make cannons.. I'd have to look it up.. I know one country, I want to say Spanish, used a metal to make cannons that was more expensive and it's non-magnetic. If you find an iron cannon, it's most likely English, Dutch, French - it all depends on the time period.

I believe they were made from bronze, rather than copper.
