[QUOTE=TheLongshot00;. Here is the question, which is more important for collectors if I sold it one day? The accuracy of the barrel (as far as shooting)? or having the correct matching barrel for the rifles reciever? Thanks for your answers in advance.[/QUOTE]

A collector would be more interested in having the correct barrel. But the barrel should match the rest of the rifle in regards to wear. You wouldn't want a mint barrel on a rifle that had quite a bit of wear nor would you want a barrel, such as you describe, on a rifle that, otherwise, shows little wear.
