Looking at the design of the gun and the stock work I would say the gun has been around for some time and that when it was built that the Marine FN was just another good action to build a custom rifle on..One could say the same thing about the many G33-40 custom rifles and the 1908 or Peruvians, but the fact is they were some of the best and quite popular in their day, but today an original one would be worth quit a bit...I personally would convert one to a custom rifle anyway, not being a collector I have ruined many a G33-40 for a happy client...I have little use for military rifles as long as they have enough of them for display here and there.
