What would be the serial number range (ex: 12XX, etc.). I have one in .375 H&H that I would like to see how close the range is. I suspect mine is from the 1950's. You don't need to supply all the numbers, just enough to see the range. I note this is a true commercial action with no charger or thumb slot. My .375 has both the three position lever safety on the bolt shroud, and a side thumb safety for use with scope. Mine has not had a scope, but is drilled and tapped. The reciever ring has the stylized FN logo.
Very nice vintage FN.
