Antique 1920's Triumph Socket Wrench Set No R-8 - $300 (Independence, MO)

This tool set was my father's.
Vintage Rustic TRIUMPH wrench set in the original Wood Tool Box No.
R-8 Wrench Set.
Made By Triumph Specialty Company New York.
Research reveals that from July 1920 to May 1922, Triumph was aggressively advertising various wrench sets in numerous newspapers across the country.
The sets in these ads were sometimes identified by a letter-number designator (including No.
R-7, No.
R-8, and No.
F-2), as in this ad from January 21, 1921 in the Dixon, Illinois Evening Telegraph.
This set came complete in a nice wooden storage box.
Measures 12 3/4"X 6 1/4" X 3".
The decal on the inside lid of the box is in great condition and readable.
The extension is marked Made in USA.
No, not that Triumph.
I haven’t been able to establish exactly when or by whom Triumph Specialty Company was formed, but I can state with fair certainty that there is no connection between these socket sets and the British motorcycle maker.
