The Model of 1908. Typical pigeon and inanimate target loads then were 1 1/4 oz. 3 1/4 Dr. Eq. - OUCH!

Trapshooters, being trapshooters, frequently added or replaced pads, and WR very likely provided any period pad requested; which pre-1910 would have likely been a Silver's. Other pre-WWI pads used in the U.S. included the Y.C. (Young & Cadwallader), Funkes, Huntley Shock Absorber (Omaha) and “Perkins” Recoil Pads (both advertised starting in 1915), Tryon #6, and the American Silver pad (sometimes called Grieb c. 1908; possibly by the Ajax-Grieb Rubber Co.)

Not sure what pad this might be. Is that your FE?
