Yes, Smith & Wesson also made a No. 3 that had been modified to the specifications of Major George Schofield, a cavalry officer. This was an attempt to obtain military contracts for the revolver. The Schofield revolvers were chambered in .45 Schofield, which is a shorter version of the .45 Colt cartridge. From my reading it seems like Smith & Wessons reluctance to chamber the gun in .45 Colt resulted in its not being widely adopted by the military.
