The proposed E-series of tanks was Germany's attempt at creating a standardized line of armored fighting vehicles that would incorporate interchangeable parts. There were to be six weight classes, designated E-5, E-10, E-25, E-50, E-75, and E-100. Only the E-100 got off the drawing boards, and even then it only made it so far as a turretless, engineless chassis and suspension. There are rumors that three E-25 hulls were manufactured, but they have never been documented.

The E-25 was a turretless design, looking superficially like an overgrown Hetzer tank destroyer. In the 25-ton class, it was designed to replace the Panzer IIIs and IVs in service at the time. It was to have been armed with a 75mm main gun.

Trumpeter's E-25 kit is sharply molded in light gray plastic, and features both rubber belt-style and plastic indy-link tracks. An optional roof-mounted machine gun turret is also included (as seen on the vehicle in background of the box art). Comes with a nice fret of photo-etched metal detail parts and decals for a fictitious operational vehicle. A great "what-if" project!
