I've got the Modelcraft one, which has Blue Tank molded on the hull bottom. I believe it is the same one as the Nitto kit. The kit looks like a conglomerate of other kits. The hull looks like it is based on the M26/46 hull, possibly an M41 hull. The tracks look like Leopard tracks, only narrow. Box art shows track looking similar to the M41 track, as well as a molded on set of spart track blocks on the cab roof that look like M41 tracks. AMPS kit reviews say it can be built up nicely with parts from 2 M-24s and a set of M-24 tracks (might be the type hull too) and photoetch. Got mine from Squadron for $8.99. It has possibilities, especially if you have a turretless M-24 hanging around.
Directions say it was developed late during WW2 and did not see combat, but was used during the 50s and 60s, pulling artillery. The suspension comes with little springs to give it tension and it looks like it was motorized at one time.
