About time. Trumpeter's original kit with Mike Rinaldi's speculative turret was fun, but this was the design they had actually intended to build, had it been approved for production, It has the Maus II turret with the flat front and a rangefinder. The secondary gun was above the main gun instead of alongside it.
In reality, the more powerful engine called for in the plans never appeared, and the E-100 would have been absurdly underpowered with the Tiger engine. One suspects the side skirts would have been ditched early on, had it ever reached service.
