Forgot to ask,
Ksoc,did you buy your 76mm gun or did you turn it yourself?And was the 76 used in the same turret as the 105 or was it just in the T23 turret?
I have thought about turning up a 75mm gun as I know it was in the same turret and mantlet but can't find any dimensions for it.

Panther F thanks for the info.Looking at the pictures it looks as though 76 was only in the T23 turret.

Thanks for the help.
