Re: hopkins & harrington what they were worth
It's called inflation, or a government that keeps spending more than it takes in.
Consider that c. 1900, the average manual laborer got about $1 per day. My grandfather and great uncle were stone masons, a skilled occupation, and were paid about $2-2.50 a day. A cowboy or soldier was paid $.50 a day and his keep.
A Colt SAA was around $13 mail order, a Winchester Model 1892 was $18. No matter what the movies show, few cowboys carried Colt SAA's or Winchesters that cost a month's pay.
I often have used a figure of 1::40 for comparison of 1900 to modern dollars, but that may be a bit low today. But even at my $40 conversion figure, those guns were the equivalent of $100, the Colt the equivalent of over $500, the Winchester of $720.
