Largest arsenal model cannon I've seen

[cannonmn]

 
Barrel of this model weighs 45 Spanish pounds, is about 27" long.  All of the materials in this model are the same as they would be in the full-scale "production" cannons, except perhaps in this one, the wheels are bronze vice cast iron.  I think the reason for that is that the Spanish Royal Cannon Foundry at Manila handled primarily bronze, and I'm not sure if they were set up to do cast-iron.  Hey, the bronze wheels look better anyway!  More details, link to 15-photo slideshow here:

Nice work for the time. Noticed its not a knew cannon, but in great shape.
