Could very well have a short chamber as well in that time frame of manufacture. I think the 20 gauge was 2 5/8 inch as standard around the turn of the century. Usually a "choke" bore designation on those old singles meant full choke. The Feb.27, 1900 is probably a patent date not a manufacture date. I don't think an H&R from early on would have an ejector, the early models had only extractors that simply raised the empty out of the chamber. gunsaholic is in the ballpark from the information given for value.
