I've been searching for any info whatsoever regarding a bronze 6-pounder field gun, with the "SNY" script logo on the breech, for "State of New York." No luck in 8 mos. of searching. I emailed the New York State Archives with no results. I also hit up the New York State National Guard historians, who had nothing.
I'm well aware of the practice during the period of this piece, with state militias, of turning in the old, worn out pieces to the founder so the bronze could be credited to their accounts. In MA, anyway, Revere gave 25 cents a pound credit toward the price of new guns which was 50 to 55 cents a pound. I think this cannon is from the period ca. 1800-1840. It was fitted for the Hidden-type percussion lock, which means it was still in service ca. 1845. It was not made for the lock however since small parts of the mouldings had to be filed away to fit the lock.
I've checked Revere's records pretty thoroughly going back to the Rev War period, and they show nothing done for the State of New York, although they cast guns for many other states.
As you can see the piece shows quality workmanship, so I suspect it was made by an experienced cannon founder, but which one?
The only marks on it are the SNY logo, the number 6 on the chase, and the weight mark on the breechface. None of the few known Revere miitia pieces has any indication of a maker's mark. There is nothing about the style of this piece that is similar to known Revere pieces (they look "thinner.")
Any help you can give to finding any documentation on this piece, or another identical piece, is appreciated.
