Q is for Question Time - Rhine Find, Saved from the Oceans!

Reader Sylvia found this in the silt of the River Rhine and asked after it, while I'm sure I have some flats with similar two-part bases (with heavy machine-tooling marks), I can't even picture them at the moment (with my eyes shut - which usually works), so does anyone recognise it?

Semi-flat frog musician, who I suspect is polyethylene; to have retained all the guitar-string tighteners on it's way down the Rhine? Were there some Italian toy soldiers with those bases? Anyway, if you recognise this, Sylvia would love to know more about it . . . premium?
