I've heard it said that any non-original rifle is worth the sum of the prices of its parts. On the other hand, some prize a restoration accomplished by putting together a bunch 'o parts that are from the same period and are willing to pay a bunch.
Most of these rifles are more emotional items for those who acquire them. The decision to restore or not boils down to the owners prerogative. From there, desirability varies with the audience. There is, however, one constant in the universe: There will always be collectors who have little tact. You have a gorgeous rifle, looking very much like it did when it was issued to its first soldier. Display or shoot it with pride.
