Fixing the Sherman Hull

Rear side view of the Z-202 Roco Sherman tank in HO scale.

A very well done model, except for the rear engine deck.  It has the rectangular part just behind the turret that is indicative of the M4 with Continental engine and the two grilles just behind that of the Ford engine used on the M4A3 Sherman tank.  Needless to say, it can't have both engines so the problem needs to be fixed.

I have an old Heiser Models Sherman upper hull, with just the rear half of the hull. 

So I cleaned up the edge of the Heiser hull, cut the Roco hull in half and replaced the Roco rear hull with the Heiser rear hull.  I then put a small disk of plastic on the spot were the turret goes to raise the turret up about 1/2 of a millimeter.  The turret won't turn freely unless it is raised up a little since it sits differently on the Heiser hull part.

Here it is installed on a Sherman flail tank.
