Swiss Panzers: Pz 58, Pz 61, Pz 68, and everything based on them

[dy031101]

I'll start this thread with a couple of items.

First, does anyone know the turret ring sizes of the Pz 61 and/or Pz 68?  Thanks in advance.

Second, I was told that the below picture is a Pz 68/88 that received on a trial basis further upgrades that included a 120mm gun.

IMHO this gun is L7 105 mm.
