Solid little model with quite a few operating features.
It is a vintage Revell 1958 model kit. I watched over my dad's shoulder as he pieced this thing together back in 1959. I wanted to maybe experience his thoughts as he read the instructions and completed the build. I bought it more or less for the nostalgia of that era of time.
I purchased this kit when I was a kid in 1956. I saw it had to buy it. There are quite a few of them on Ebay most have a sealed box. It is finely made parts assemble easy with good directions. You can paint it or not looks good as is. The
crew of two and three soldiers are highly detailed a should get some paint. The box art is great. This is 1/40 scale and should fit on an o gauge flat car. This was a precursor to many a fine military line of the period.
