I have been trying to find the Harrington & Richardson Arms Co. patents that go with the patent dates stamped on a little 44 Caliber single barrel I have. Searching by date is a pain!! Sure wish these old shotgun manufacturers had stamped Patent Numbers instead of dates on these old guns!!

At any rate the one I haven't been able to come up with is Feb. 20, 1900. Anyone have a suitable Patent to go with that date?

Thanks in advance.
