Marx Battleground and Training Center Playset Pieces - Marx Short Barreled Firing Howitzer OD HP

This is basically a cut down version of the long barreled howitzer posted the past few days. There is a precedence of course and this thing looks a bit like the M3 105mm howitzer to me. That said, if you find that it looks like a different howitzer let me know - I just didn't feel like plowing through the Internet searching for look-alike's. The firing mechanism is different on this short barreled version: the shell firing spring sticks out of the top of the barrel vs. the breech (as in the larger howitzer).  Be Blessed and Relish Life!

Here's an original sprue of shells that would have come with either the long barreled, or short barreled howitzers
