Looks like it's game piece from that famous game . I can't think of the name but it's a Milton Bradley game or a prize from a old Cracker Jack box... But judging by the size it a lead or pewter play piece from maybe the twentys. IMHO , Woodstock
I would say WW1 howitzer. "Tin" soldiers of the time. I dug this little dough boy up in my back yard a few years ago and it looks like they might have had some fun together. I believe molds were sold and you poured how ever many you wanted. I think this little soldier is lead. So- post WW1. Maker?
Agree with other TNetters, this is a two dimensional field howitzer common in many toy soldier sets between the SpanAm War and WW2. Many American and German companies used this exact, or similar mold, with the offset wheels. This cannon would have had a barrel extending past what is now the tip of the bore. An American company, Soldiertoy (1929-1936,) used it in their sets, for example. Always great to find toys! Happy Hunting, Sub
