Rudi asked: "Is there an economist among us that could give a ball-park figure of what the 1890 Farrow rifle would have cost in today's dollars?"
I am and I can.
The inflation calculator, at
(You need to Login or Register to view media files and links); says that $1 in 1890 is $17.71 in 1998.(1999 isn't over yet, making calculations for this year tough)
(The pre-1975 data are the Consumer Price Index statistics from Historical Statistics of the United States (USGPO, 1975). All data since then are from the annual Statistical Abstracts of the United States.)
So the short answer is that the Farrow rifle that sold for $50 in 1890 should sell for $50 X 17.71 = $885.50 in 1998. The "Cost of living" multiplier is 17.71.
Economists don't like to give short answers about prices over time. Here's why.
(The following from the "Old Colony Memorial" from 1890, copies of the Plymouth Town Report, and some other reference books. in the Plymouth MA public library.)
In 1890, coal was advertised for $6.25 per ton delivered, today's quote was $171 per ton delivered. $171/$6.25 = 27.36 is the "Coal " multiplier.
The 1890 Old Colony Memorial was 5 cents; today it's $1. $1/$.05 = 20 is the "Newspaper" multiplier.
The Governor of Massachusetts made $5000 per year in 1890, and makes $90,000 per year today.$90,000/$5000 = 18 is the "Governor" multiplier.
Strawberry, Blackberry or Raspberry vines were 10 cents per dozen in 1890; and are $1 each today. $1/(10/12) = 120 is the "Berry" multiplier.
In 1890, Piano tuning was (upright) $2.50, in 1999, $65. $65/$2.50 = 26 is the "Piano Tuning" multiplier.
In 1889 the Plymouth Superintendant of Schools earned $1200 per year, in 1999, $100,000. $100,000/$1200 = 83.
Massachusetts Legislators made $650 per year in 1890, $46,000 per year in 1999. $46,000/$650 = 71.
In 1889 the High School Principal made $1500 per year, in 1999 the job paid $79,896. $79,896/$1500 = 53.
