Thanks all for the nice comments and pictures of your own Springfield's.
I thought some might find the attached scan amusing. It's from a novelty reprint of a 1908 Sears & Roebuck catalog that I've had for years. It's over a 1000 pages of the typical consumer goods that the American public would have been ordering between the turn of the century and WWI. Clothing, hats, ladies' corsets, patent medicines, wood burning cook stoves, furniture, saddles, harnesses, farm wagons, and even all the pre-cut materials and plans to build a 3 bedroom house.
Included in the firearms section were some surplus Springfield's--both a two band musket and a carbine. One could get the musket, 20 rounds of military surplus ammo, and a bayonet (if one wanted it) for the grand total of $2.75 plus shipping. The copy states that they bought a large quantity of the rifles from the Rock Island arsenal. The carbines were a dollar more because Sears had gone to the trouble of having them made by cutting down some of the muskets.
The listing on the rifle claims that these were the same guns used in the civil war, and the illustration looks more like an M 1866 due to the early leaf sight. However the picture of the carbine looks like the model 1884 since it has the later Buffington rear sight. Obviously, at those prices the accuracy of the illustrations and information were not that important.
To put this in perspective--in the same section of the catalog, a new Winchester model 94 sporting rifle in 30 WCF with a 24 inch octagon barrel was listed at $15.53 while a Colt SAA standard model or Bisley style were listed at $15.50--both in either 7.5 or 5.5 barrel lengths.
Using an inflation calculator from 1908 to 2019 that I found on the net.
$2.75 is $76 in today's dollars
$15.50 is $430 in today's dollars
There must have been a recession in 1908 since the calculator I used shows inflation at a negative 2.13 %.
I have an original Winchester catalog from 1905 which shows that same rifle priced at $18. Sears only offered the single configuration mentioned, so they may have gotten a discount from Winchester by ordering a single model in volume. Anyway, Sears was sort of the mail order version of Walmart at the time, so it was hard to beat their discounted prices on anything.
