Was contemplating a Chilean M-60. Is the counterweight on the turret the same as the the M-51? It looks smaller than the 105mm gunned turrets. My eyes?
The M-60 Sherman were based on M50s and retain the original turret of that vehicle, the M50’s turret was modified 75mm turret. I think that there were some M51s (or M4A1 based M50s) that had the 60mm HVMS gun, but that was a complete turret swap (if it was a M51).
