The tracks look a good bit like a miltary Weasle..
In the discription it states it has a two speed rear end, also a weasle feature. Unfortunatly it doesn't secifi what engine or trasmission it has. Would be alot better if the seller would tell us more about it. Maybe a question should be asked, if interested..
My guess is that it is a Light Foot, a semi custom builder, who ironically used Weasle parts in many of his riggs..
