I've just spent like half an hour looking at the first picture of yours and comparing with literature and pictures in here .. and after all I'm not fully sure on which letter it is on your barrel. Only on the barrel is correct for this rifle, no worries on this. If you want to compare yourself, here is another ce44 from the p block, where the letter originally was misread as n block:

Secondly, as others have pointed out, the scope rail on your rifle is different to the scope rail that is known for other "swept back" rifles. The others known have a single round hole in the middle of the rail whereas yours has the rail in a G/K.43 style with interrupted cut. Also I noted it seems the rail on your rifle is sitting a bit more to the rear.
It would be appreciated if you could take the pictures with natural daylight and show all what you have. Also you mentioned the stock is sportered - does it at least have the matching number in the barrel channel? Not knowing where you got it from you may also consider it worth trying to ask wherever you bought it if they possibly also have a scope mount and/or scope for your rifle.
Regarding your question: it would have most likely carried a laminate stock with the small takedown disc and cupped buttplate. You can also look at the pictures of this o block ce44 to get an idea on how the stock should had looked like:
