Originally manufactured in 1978, this pair of Colt Mk. IV Series 70 Gold Cup National Match pistols were beautifully upgraded and embellished by Master Engraver Ben Lane Jr. (1940-2023), who signed his work on the frames under the grip panels with his typical conjoined "BL" marking. Lane was a Colt Master Engraver, founding member and past president of the Firearms Engraving Guild, and a founding member of the Colt Collector's Association. This very attractive pair of pistols show matching engraving featuring near full coverage vine scroll engraving on the sides of the frame and sides of the slide, while the upper surface of the slide and lower surface of the frame show a more matte nickel finish. The initials "J.F.B." are engraved on the left forward portion of the frame on the "A" gun and on the right forward portion of the frame on the "B" gun. The left sides of the slides have the three-line model and caliber marking followed by the Rampant Colt, while the right sides of the slides have the two-line Gold Cup National Match marking. The single line address and serial numbers, which are only 126 digits apart, are on the right side of the frames. Both of the pistols are fitted with Patridge blade front sights, Elliason adjustable notch rear sights, and adjustable serrated triggers. They are both fitted with smooth ivory grips that have a scrimshawed eagle on one panel and the initials "FB" on the other, the designs are mirrored on the right and left between the two pistols.
