Seeing Louis' latest build adventure made me recall seeing this on eBay a few days ago.
I have paged through David Doyle's 2 vol. set on U.S. Halftracks and can't find anything about it. There are a plethora of different version pictured but not this one.
It is pretty cool looking however. Has anyone seen any prototypical pics or info?

I also have a Torro M16 in my "stuff" and will be watching Louis' build. I will likely use the ElMod plug and play board specifically designed of the M16. But Louis may change my mind with his build.
