i have read the threads, but would like some support. The top of the barrel reads "Henderson & Richardson arms company Worcester mass patd oct 4th 1887". The serial number under the handle reads 2404 and on the cylinder, 404. It appears there may be small markings on the right side of the barrel, but they may be from age. I'm new to revolvers and handguns and very naive. A precise model, expected year of manufacturing and any other interesting info one may have would be greatly appreciated. I think it's a .32, but that's about it.
