HI guys, I'm making a Reg 4th Panther A in Italy. But I am not sure which engine vent cover I should use. Any idea?

You can use this build as reference:

Cheers,

If you're referring to the round grills over the engine fans, either or both would be correct. It appears the spiral pattern came first (replacing the preproduction spiral pattern with the "complicated" edge design in late spring of 1943), but the radial pattern appeared shortly after, either due to a change order, or perhaps just reflecting different vendors for the part. By the time the late Panther Ausf. A reached production, there were stocks of both grill types on the production lines and both were used interchangeably, sometimes in mixed sets (with no preference as to which version went on which side).

Thank you guys
