A mate of mine bought this 20mm case but with odd rim, wartime dated. Anyone seen this before.

While I cannot ID your case exactly, whatever it is, it seems to be incomplete.

This is an unfinished (I think) 20x110mm Hispano case. It seems finished other than the rim not being cut and the mouth / neck trimmed. The primer hole and flash holes are drilled as well.

I have 1 also a hispano unfinished measures 20x112 primer pocket drilled but no flash holes and stamped RH 1942 20MM
 
As Big Dave says, its a unfinished 20 x 110 Oerlikon. 2 things give it away. 1 The head stamp 2 The shape of the shoulder.
Cheers
