Tim I am deeply impressed by your paint job!
Absolutely first class and spot on a Normandy Panther look - I love it!
Also impressed how that tiny table can hold the Panther weight...
If you are aiming at a 1SS one I have reason to believe the big turret numbers was red outlined in white, at least for some company in that unit
(look at the well known befehlsPanther #R02)
But not sure as photos of confirmed 1SS Normandy Panther are rare and often seen with the spare tracks hanging and hiding the numbers. There are also reasons to believe that unit simply did not have other side numbers then the smaller ones at the mantle sides.
They did how ever have the small numbers also at the rear of the turret.
Here is a photo of the Panther seen at War and Peace last year numbered as a 1SS one.
To confuse you even more

the 1SS had definitely black numbers outlined in white during the Ardennes.
I think you shall go for the white outline but if red or white numbers I leave up to you...
Cheers
Kent
