Dean, what a wonderful gun! Those barrel keels (4th pic in second batch) would have confirmed things for me.
Just for comparison, I had an 20b Flues at one time, wish I hadn't sold it. Just a Field grade made ~ 1920 but in 99.5% condition, possibly unfired. Its barrels (not Krupp) were stamped 0 and 4 which would normally indicate Cylinder and Full chokes. But as we know Ithaca usually didn't restamp choke numbers when gun was ordered with more open choking. Chokes actually measured .002 and .014, thus the left barrel with ~ 2.5" long tapered-choke had been opened to Mod. Weight 6^2 with 28-inch tubes. Anyway ..... one of the guns I wish I had kept. Yours is a very nice find and I'm happy for Kathy and you.
