With or without a scope, it's worth whatever value you put on the use you will get out of it. And that depends also on how hard it is for you to come by the money it will cost and what else you need the money for.
(Of course all original parts makes a rifle most desirable to the more serious collectors, but a milsurp restored with genuine replacement parts is a quite authentic piece - a lot of them got like that in their service life, so for some collectors that is attractive enough. Again, it depends on how much it costs to get it there, and with patience and luck, some get there for a reasonable cost. ) Like I said, one should think about it first, and you did, so that's all right.
