From the 1972 Gun Digest:
Colt Trooper Mk III $135, with wide spur hammer and target stocks $142. This was in the section "Revolvers Over $90", i.e. the high priced zone.
In other news:
A Colt Python in royal blue would set you back the princely sum of $190 which was, in fact, a lot of money.
A S&W Model 29 was $181.
Lesser guns for the run of the mill shooter were:
Colt Mk IV series 70 was $125
Ruger Standard auto was $47.50, $53.50 if you wanted checkered walnut grips
S&W Model 41 was $131.50
Colt Detective Specials, Cobras, Lawman Mk III and run of the mill Smiths like the Model 10, 14 or 15 cost from about $110 up to around $135 with fancier options.
These are MSRP, of course, street prices would be lower.
The inflation of the late 70's drove all prices through the roof. A loaded Corvette in 1970 was around $4,000. My sister bought a three bedroom house in a nice neighborhood for $40,000 around 1972-73 and sold it in 1979 for $90,000.
