Marx & possibly other makers. The largest are about 5" to 8": 3 silver, 2 light grey, 1 dark grey & 2 light green. 2" to 6" long: 3 darker grey, 21 light grey. The next group has 9 & are silver & range from about 2 1/2" to 4 1/2".
3" to 5" : 6 green, 2 red, 8 blue. 3 " to 3 1/2": 13 brown & 2 tan.
The remainder are about 1 1/2" to 3" & has red, green, yellow, grey. There's also 6 red cavemen that are about 1 1/2 tall. They're in very good condition with no missing or broken parts. Since I'm no expert I'm not sure if all of them are Marx & if some of the smaller ones are from the 70's.
