Possible Ames foundry example 18" overall, 20+lbs, 1 1/4" bore. Photos from the vendor plus one of mine showing the markings on the muzzle. Fortunately I know of a craftsman who makes carriages for all types of artillery both full size and scaled to fit. I will be updating this post when the carriage is completed for this example. If anyone knows what significance of the No.37 lettering on the muzzle denotes please post. Any information on this example would be appreciate.Thank.
