Regarding the 'affordable workingman's rifle.'
Looking at a reprint of the 1875 Winchester catalog (the first year the Model 1873 was cataloged) the least expensive version available at the time was a 20" barreled carbine, which sold for $38.00.
The most expensive was a fancy Sporting Rifle with octagon barrel, set trigger, curly grained and checkered wood, for $60
A standard model with 24" round barrel, plain wood and no set trigger was $40.
Using one of the many inflation calculators on the web, in 2015 dollars that would be $826.09 for the carbine, $1,304.25 for the fancy rifle, and $869.57 for the standard model.
Not as expensive as the current Miroku rifles, but certainly not cheap either.
Looking back further, the standard price for the 1860 Henry rifle, the predecessor to all the Winchesters, was $42 in 1862 (the first year they were produced).
$1,023.81 in 2015 dollars.
When first introduced, these rifles were cutting edge technology, and if you wanted to own one you had to pay for it.
