Vimy Ridge,
My FN has matching serial numbers. There are three # on the entire rifle: On the receiver, the bolt and on the original walnut stock (inside the barrel channel). the rest of the parts all originally belonged to that rifle except of course the barrel, which the Israelis swapped out to a 7.62 1958 dated barrel.
FN made these new for Israel in 8mm postwar with the IDF crest engraved on the receiver. These rifles had walnut stocks, a narrow lower band with a swivel and a slightly different rear sight. I have never been able to find any info on exactly when these contract rifles were made by FN and their production total.
The rifle now sits in a new old beach stock with an Israeli wide lower band. Of course I still keep its original matching stock set and narrow band with the rifle. If i had the original matching 8mm barrel that was taken off, this would really be something.
