Very rare and very attractive outfit. It's serial #1449 is stamped on the left side of the barrel. The silver plated grips are patent dated "Pat. Apr.28.74 " on the left grip. They were mostly made for DeGress in Mexico City and are quite rare. The pistol retains about 20-30% nickel finish while the grips retain about 30% original silver with the remainder exhibiting a nice blending patina. The flap holster fits perfectly and was obviously made for this pistol.
