Vintage All Brass Miniature Cannon Gun Carriage from PortugalApprox 11-3/4" from front to back and approx 4-1/2" tall. The diameter of the muzzle opening is approx 13mm. This piece is over five and a half pounds of solid brass and has great detail. Notice the two Koa fish on top. The brass is not nearly as bright as my camera flash makes it look. Marked "Fecafe Portugal" on the bottom.
