NAPOLEONIC-ERA FIELD ARTILLERY

My best guess is this is a Napoleonic era artillery piece. This is said to be a 1:45 scale metal and wood kit from "Scale+" of China, bought on AliExpress for about $15.
The gun carriage and axle and wheels are solid wood. The fittings are metal. The gun is brass. The cannon balls in the wooden monkey are steel. I should probably paint them black.
I added metal straps and chains to the carriage.
The wheels have thin strips of metal cut from wine bottle tops as the tyres, painted black metal by Vallejo.
The base comes with the kit and is painted with Floquil spackle "Gravel Gray".
