Huh, very interesting... I have to admit, some parts look slightly similar to my design but at least there's now one in resin that's marketable. I'll have to see if I can't get my hands on a set and compare them. Also, the T110E3 here was actually based on proposal #4 for the T110 heavy tank program. WOT mistakenly calls it the "T110E3" while their version of "E4" never even existed on paper. All previous design proposals (up to and including the actual E4) were all heavy casemate types with the E5 being the only turreted design in the series. The E5 was also the only design of the series to be made into a full size wooden mock up. All of them were heavy tank proposals, by the way, none were designated as tank destroyers.

Oh goody, the American version of a "paper panzer". Oh, why not...

I'm kind of surprised there isn't much interest in this, judging by the lack of comments here. It seems pretty interesting in my opinion.

Yeah, for a WoT beast the silence is odd. Looking in detail it appears to be based on a carved-up DML upper hull, and there are sufficient differences in the casement to say it is not copied from your parts - just modelled from the same references is my guess. Gotta say I do like your CAD!
