Let's do cannons #4

Here's another .30 caliber piece. The barrel is brass, and the carriage is cast iron. The problem is, while both are old, the barrel is not original to the carriage. Someone must have thought this combination worked, but it does not, as evidenced by the disparity at the trunnion.

However, the skewed aesthetics of the piece are not off-putting - I imagine the original counterparts were lost during antebellum play, so much may be forgiven...
