I am going to build a Panzer IV, using Tamiyas kit Pzkpfw IV H Early Version (suitable for Ardennes based diorama??) and want to add a Jordi Rubio aluminium barrel
Is this the correct one (from the rubio site)
TG-05 75mm KWK L/48:Pz.IV G-J, Stug.III/IV
or do I need this one:
TG-46 75mm KWK L/48: Panzer IV G-J
or are they the same... sorry to look like a noob, but I have been building mostly aircraft - trying something different now, but I still need to be a (bit) correct

cheers!
