Sherman tank shown on Marklin 6-axle flatcar for size
comparison
The Sherman in Z scale is 31.9mm (1.25") long (including the gun), 11.9mm (0.47") wide and 13.1mm (0.52") high.
The tanks are cast in a grey plastic which has ideal properties; it
is light yet strong and accurately reproduces the full detail of the master prototype. Being light (each tank weighs about 3 grammes)
allows the tanks to be put on Z scale wagons and pulled by locomotives.
