Coyote,
I agree with some of your assesments, but I repectfully disagree with your "universal" statements.
Not ALL H&Rs were "2 dollar guns". H&R and the rest of the manufacturers you cite made, mostly, utility grade - blue collar guns - and they were not made of "cheap" materials, nor poor workmanship, nor lesser attention to detail.
I've been researching H&R firearms for right around the past 15 years, collaborating with the late Bill Goforth on his H&R book. I've handled and examined well over a 1000 different examples; I currently own over 400 H&Rs and have owned at least 200 others; my examples run from pieces made in the mid 1870s all the way up to the late 1990s. From my research and examinations, I can say with conviction that there are many examples that contradict your assertion that all H&Rs are cheap and poorly made. Not all were inexpensive - there were several series of very accurate pieces that cost as much as S&W and Colt target pieces and in fact surpassed those vaunted manufacturers in domestic and international competitions.
You cannot pick the "cheapest" pieces and paint the entire spectrum with one color.
S&W made lower cost hand guns during the period in question, just as did the middle road manufacturers. If all the production of H&R, IJ, H&A, etc. were junk - those companies would not have lasted for the many decades that they did exist (IJ and H&R existed for over 100 years.)
As to longevity and as to how many are still working - well, I've got those early 1870s and 1880s pieces that still work as intended and having been taken care of are still tight and have very nice finishes.
Your sampling was selected to simply support your "universal" statement and as such your statement that these types of guns were only good as "wall hangers" is totally invalid.
