No, I mean, without a maker's mark, it's hard to be exact. The iron used is of a much 'cheaper' quality than that of the British 18-pounder I conserved prior. It's very soft and hasn't held up as well as the British gun. Now, I'm not too sure if that's because the early American gunfounders were still correcting their gun casting techniques and material or if British iron and American iron at that time were of two different qualities.
