A.J. Deer Co., Inc. in Hornell, NY

My grandfather Elmer Chesebrough (1883-1940) was a butcher and traveling salesman, mostly in MI but perhaps also in Milwaukee, WI and Toledo, OH..I have from my grandmother's records a 1905 "Illustrated Catalog of Royal" equipment, including "electrically operated coffee mills, meat choppers, meat slicing machines, peanut butter machines, coffee roasting machines."The company motto apparently was "We are originators and not imitators."
The 44 page booklet is in excellent shape.Does anyone have any information on this company?Does it still exist?
Thank you for any response.
