Sherman or German

So part of my collection is one-off vehicles.  I use them as museum pieces or experiment types.

My plan is to use this as a Sherman test bed vehicle.

The US Army used it to test a new engine, new suspension based on the German interleaved wheels used on many of their tanks and halftracks.

That's plausible because the US Army did put a German interleaved suspension on an M24 Chaffee light tank.

And all through the war they were putting in new upgraded engines.

And compared to this Roco / Heiser Sherman it is not too bad.

Note the size, and the rear engine deck is not too bad either.
