I stand corrected. The barrels have not been struck after manufacture. All the barrel engraving is intact and sharp and so are the letters and numbers. There is a gold band between the short rib and the main rib. The gun is an ejector gun.
It does say "choke" on the barrels about 1-2" in front of the flats. It also has the serial number there too.
I am curious of the significance of the 2 teeny tiny AF with a crown over each on each side of the flats toward the front. You can see it on the first four pictures.
Bob just contacted me. They have no record of this gun but he is visiting the site right now.
