Just a quick note: if you’re planning on doing this, by far and away the best source for the 75mm parts is the PSC M4A1 76(Wet) kit.

Why?

Well:

a) the bits you need are specifically marked as ’not required for this kit‘. (Good old PSC ‚almost generic‘ sprues!)

b) the British used the Sherman IIA (aka M4A176(W) in Italy, so you can use the rest of the kit.

Problem solved 😀
