I have been offered these two high explosive projectiles with a description of them being post war French made M42 high explosive shells for 76mm armed Sherman tanks. I suspect they might actually be for the 75mm gun on the AMX-13 tank - since the HE had a much lower velocity - only one driving band is needed. I would greatly appreciate your help in identifying these. If anyone can show the CN 75-50 ammunition specifications from a manual, that would be wonderful as I have yet to ever see such documentation. Thank you.
