Having spent a few days on and off looking at various artillery pieces I think the original picture is an amalgamation of different artillery parts. The wheels certainly look like the Crimea era. The cradle could be circa WW1 it certainly looks like it has been reworked for display purposes. (ref Halifax image single) and the barrel looks earlier than ABW.....A cut and shut cannon . I may be wrong but I couldn't find an exact likeness of it anywhere on line.
You only live once, but if you do it right, once is enough.
