Outing, 1898
https://books.google.com/books?id=D2I-AAAAYAAJ&pg=PA94&lpgThe big trap event, the Grand Prix, excited an unusual amount of interest, and for the first time since 1889 the coveted prize has been won by an Englishman. Out of 139 entries, only 37 were in at the end of the third round, which speaks volumes for the speed and shot carrying powers of the famous blue-rocks.
The winner, Mr. Curling, killed twelve straight, using a gun by Branequart [
sic], of Brussels, and “Schultze” powder. His winnings consisted of 21,340 fr. and an objet d’art in the form of a costly tea service.
Signor Asti-Cesari and Marquis Saragua divided second and third, 19,900 fr. “Dr. Pascal,” fourth, took 5,100 fr.
The conversion for French Francs to U.S. Dollars in 1900 was about 5/1.
21,340 fr. = about $4,268
