The turret is similar to a modern M-1, but slightly thinner.
The chassis is rectangular, with a rounded glacis plate (or front) that is slightly wider than the chassis. Looking down on it, imagine a rectangle with a large square in front with a semicircle attached to the front of that.
The other hover tanks I found look to sci fi and have lasers not a gun.
I found an image of one on another website and I have attached it...its small though.
