Looks like it was mostly a matter of scraping off gray paint. Have to wonder what the three bars on the barrel signify ?

That's where it starts.

Interesting. I would not have expected any breach loader to have a brass barrel.
Would love to see and understand the inner workings and sighting system on those.

That looks like it would be fun restoring.

Fortunately, Trou d'Eau has gotten weapons like that off the streets in Canada.

Wow, interesting thread ,thank you. That "sliding breech block" cannon is a beauty .

I have built one "Krupp type sliding breech block" breech loading cannon tube (15/8 bore) and always wanted to do an "interrupted thread" type but got "old" before I could gather up all the parts I would need.

It’s likely Bronze (much tougher than brass), I also wouldn’t be surprised if it had a steel lining for the inside of the barrel. Definately would be cool to take a closer look at!

Since those seem to be marine/coast used guns is there a possibility of gun being steel,but bronze plated as a corrosion prevention measure?

It would make a lot more sense than solid bronze gun parts.
