What I've been able to gleen from the internet, the H&R double was made from 1909 to around 1920/21, which coincides fairly closely with the ads Dave posted.

I have a 28 ga at the house now that was in very rough condition that a friend asked if I could do anything with. I was able to freshen it up a bit and fix some minor mechanical issues. It does have steel barrels and I'll give it a test this week to make sure everything works properly.
