This is one of only 976 Bisley Flattop Target Revolvers manufactured by Colt and one of only approximately 131 chambered in .32 WCF (see David Brown's "The 36 Calibers of the Colt Single Action Army," page 190). "The .32-20 W.C.F. cartridge had good range and accuracy," wrote Brown. "It is very easy to shoot as it does not make the revolver buck as the larger calibers do." Today these scarce revolvers are highly sought after by Colt collectors. It has the correct all blue flattop frame and pinned blade and dovetailed notch target sights. The barrel has the one-line Hartford address on top and "(BISLEY MODEL) 32 W.C.F." on the left side. The left side of the frame has the two-line patent dates marking followed by a Rampant Colt. The left side of the trigger guard has a Colt factory verified proof and number "1". The loading gate has the assembly number "17", and the back of the frame has the assembly number "7" (likely a factory error). Matching serial numbers are found on the frame, trigger guard, back strap, cylinder ("6579"), and back of both grip panels ("6579"). The Colt factory letter states this revolver as being a Bisley flattop target, caliber 32-20, 7 1/2 inch barrel, blue finish, stocks unlisted, sold to Blair's Sporting Goods Co., shipped to W.B. Jarvis Co., Grand Rapids, Michigan, on October 30, 1914, one gun shipment.
