I have 2 16ga hammer guns, both found within the same 7 day period. Luck, I suppose. The LC Smith website says only 1306 0-grade 20ga. Roughly 3300 00 Grade 20ga.

Will you are 100% correct, 1306 made. That's what I get for quoting from memory. I was thinking of the Field grade.
You are a lucky guy to own to 16 gauge hammer guns.

I didn't realize the early 20's were that uncommon. I have an 00E from 1909 that is in very nice shape. It also has excellent wood for the grade. It doesn't get out as much as it should.
