Very beautiful rifle! I have found a bit of information on this FN. A Washington, DC importer, Firearms International, began importing these rifles from Germany in 1948. All of these imports had ' Chrome Vanadium Steel ' stamped on the barrel. Your FN was manufactured in 1952, as shown on the barrel. The rifle is all original, including the peep sight mounting holes on the receiver, which were added to satisfy the importer. This was done at the factory in Germany. The stock is also original. The engraving was done as a pre-FN stamping on the receiver, possibly another importer order. Some were done by custom engravers by special order. Most of these engravings can be tied to the engraver. The more elaborate, the higher the values. 1952 saw the first FN Mauser barreled actions imported into the U.S. as well.
