Description:

This rectangular white plastic slide rule has scales for sprint times from 5 to 7 furlongs; two columns for use with the average pace method for handicapping horse races; three columns for use with the highlight pace time method of handicapping; and scales for route times from 1 to 1-1/4 miles. This outer folder is marked: Ray Taulbot's Pace Calculator (/) WITH AMER-VAR; Published by (/) AMERICAN (/) TURF MONTHLY (/) 505 EIGHTH AVENUE (/) New York, N.Y. 10018; PRINTED IN U.S.A.

The slide, which fits inside the folder, bears scales for speed rating, half-mile sprint highlight pace time, and six furlong route highlight pace time. It is marked: BASTIAN BROS. CO., ROCHESTER N.

Ray Taulbot (1895–1969) was the longtime managing editor of American Turf Monthly, a magazine for horse racing enthusiasts published by the Amerpub Company. He is credited with several innovations in handicapping races, particularly by rating a horse in comparison to the overall pace of a race. He believed horses must be judged by their own speed and by how close they were to the winner. A chart on the back of the calculator allowed bettors to combine the results of the Pace Calculator with the Amer-Var rating, which took into account the horse's age, the length of the race, the amount of the purse, the time of year, and the type of race. Taulbot's methods dated at least to the 1960s, but this device was made in 1979. American Turf Monthly continues to reprint Taulbot's articles.
