Need help.
 

Hi Everybody,
I'm trying to figure out what toy I used to have when I was a kid. This toy was made in the 60s. This toy would make military vehicles and probably soldiers. You used a waxy kind of plastic that was melted in a machine. You would insert the mold you wanted and push down on a plunger that would push the melted material into the mold. You could remelt the material over and over. If anybody has any information or memories of this I would appreciate hearing about it. The scale of the toys was very small. Probably HO scale or close. Thanks for any information or memories you have. My brother and I had a ton of fun with this toy and I'd really like to find out what it was.
Thanks,
Steve

I had a version of that as a kid in the 80s that made hot wheels style cars...might be the same manufacturer?

So I was looking around after I posted that to see what exactly it was that I had and came across this:
