Home Forums Hunting & Shooting Express Rifles and Big Bores Only My First Double Rifle Came From Santa This Year

Gents,
You 12 ga = 12/70 argument makes so much sense, that I have included pictures of the barrel flats for your perusal:




Now, the hunt is on to find the proof date information!
And after some work with a good light and magnifying glass, here it is:

The number "159" stamped in fine numerals can be seen just above the last zero of "2100 FPS" and is vertical to the horizontal 2100 FPS. This number is under the right barrel flat and is the only such number that I found. Therefore, the proof date must be January 1959.
Please advise if my exuberance has again misled me.
