Photos of that project (WkNr. 1983) can be seen here: http://forum.keypublishing.com/showthread.php?125261-109E-Projects-current-status

This aircraft has been described as an E-7 on the “Preserved Axis Aircraft” site, and as both an E-3 and an E-4 in the thread linked-to (surely due to the progression of upgrades that the Germans did on the Emils during service).

Hangar 10/Air Fighter Academy already has a restored static Bf-109G-14 and a recovered Bf-109E wreck (from the Alps) on display at their museum/facility.
