Toys and Stuff: Marx Battleground and Training Center Playset Pieces

Just a little over a month ago I posted one of these exploding machine gun nests, but it was missing the metal trigger and the plastic pieces were mis-matched colors. (SIDE NOTE: Even though these are referred to as 'machine gun nests' they were also included in Blue & Gray sets as a "bunker that actually explodes"). The cobbled together piece previously posted was an expedient way of trying to get as complete a piece as I could back in the day. The last time I was actively trying to search for and buy one of these many years ago, the bloody things were going for well over $200-$300 per! Fortunately, I was able to acquire one recently for far less than that, but was still a bit pricey at just under $100. The trigger's and spring loaded firing mechanism's tend to get lost, and the plastic pieces are often broken from use, so finding an intact assembly can be a bear. And no, I did not try to test this! Why? Plastics get brittle and are easily broken and I'm not chancing breaking this!!!
