This gun is for sale again on Guns International. SN 18860 (late 1873, early 1874 - original centerfire gun not a modified pin-fire). Those are blued Damascus 42" barrels to my eye.

It was last sold by James Julia about 7 years ago:

If you need a canon, this nickel plated salt-water 19lb gun should do the trick. Price is quite good $5,000 - $30 a pound - about prime beef price and about 1/3rd of what it would cost to replace a shoulder.
