Here we have a solid bronze antique 21 mm or 0.80” bore black powder cannon, O/A length 15” barrel 14” fully proofed for an 875 grain ball and 80 grains of black but as it’s an antique you can own this without a license but of course if you want to fire it then it must go on an FAC. It’s sitting in a later Oak carriage and the whole thing is very heavy, probably 25 lbs or so. I have purposely not polished it as I know some folk like the original patina but personally I would buff it to the max. Can you imagine what this would like like polished? Awesome! I can send this direct to your home for £25 so long as you’re over 18 years of age. Please study all the pics especially the proof marks.
