Filipino cannons

[pbleed]

I appreciate the responses that have been offered. Thank you and please forgive my ham-handed attempts at communication.
I also failed to communicated in my initial post that these are MODIFIED guns that were altered to make them BREECH LOADERS. I think the smaller gun started as a Spanish mountain gun. The other one looks like a "lantaka", but I wish there was a grand synthesis of those guns. Apparently there isn't one.
Both are mounted on large - but movable - wooden bases. They are absolutely NOT gunwale sections. They look to me like man-handles field artillery.
These guns are both BREAK ACTION breech loaders that were fitted in iron frames that let them pivot open and be firmly closed when they pivoted down. I was hoping to find some precedent for that design somewhere in Asia. More than anything they look to me like BIG shotguns
