I just noticed, as I'm getting ready to complete my Cold War Europe mid sixties French, that the stats of the AMX 13 75mm gun are 3/50. This seemed a bit low, as that gun was derived from the KwK L70/75 of the Panther, and matched, from all accounts, its performance. Furthermore, a quick check of the Israeli list shows that the M50 Super Sherman's gun stats are 3/70 : that tank used the very same gun as the AMX 13.
http://en.wikipedia.org/wiki/Super_Sherman Is there a reason for the difference? If that is just a mistake, by how much need I rise the value of the AMX 13 to bring its gun stats up to 3/70?
