This model represents a 60 ton Manticore tank from Battletech or Alpha Strike.
For this model, as always I looked at several sources. For mostly looked at the old metal miniature and original line art, and changed some things about the proportions that I thought could be improved. I also lowered the LRM10 on the back of the turret and angled it up, similar to the launchers on the Manticore II. And as always, I reworked the details so they'd print reasonably well at a small size.
The model will have to be glued together - the turret can be glues unto the main body at any angle. Any basic superglue will do. I've also included a proper Battletech size hex.
