I took in trade a Browning FN High Power Safari Grade 30-06, Ser # L53x, and was hoping to get some help in dating it, from what I can tell it seems to be a 1st year production, 1969? Safari Grade? The metal is all good no rust, the ser # is in the barrel channel of the stock and matches the gun ser #.
