The Renwal kit is probably it. The did the M41 and M42 with those little spring suspension arms. Revell acquired their molds and released many of the old Renwal kits in the mid 1980s. When they released the M41 Walker Bulldog and M42 Twin Forty (Duster), they omitted the springs. Revell of Germany (using the Matchbox label) recently reissued the M41 around 1998 or so.
I still have a Revell and a couple of the original Renwal M42 kits. I think I gave away the Bulldog, but kept the M47 Patton tank. I know I still have the Revell History Makers version of the M55 Self-propelled howitizer too. When I was a kid, the Renwal kits were the "serious" models that had real working tracks, hatches, suspension, etc.
Oh yeah, got a pair of the M50 Ontos recoilless rifle tracks as well. All of thse kits were 1/32 or as they listed it ΒΌ"=1'.
