I got this kit some time ago in a mystery box and it was indeed a total mystery as to what it actually was. It came in a bag with multiple metal parts and 3 chunks of resin. Anyway, it eventually came together and I learned it was an SS-Ki by Warlord games. I'm not one for armour really but it was not much of a challenge to put together (despite a lack of instructions) but fun non the less.
This vehicle was essentially a Japanese 'swiss army knife' able to clear mines, lay bridges, flame stuff and recover other tanks. Not a lot else to say really. It's a funny wee fella, very weighty and I suppose an asset for table top gaming.
