I have a colt saa chambered in 45 colt. It is custom engraved full coverage not just partial like I have seen on most engraved saa pistols. The engraving is not typical scroll work, it is oak leaves and acorns. There are no markings on the gun as far as a hint to the engraver. The grips are custom ivory and i have not seen any grips like these before. The grips have the initials JLO engraved into a side shield. I called colt and found out that this pistol left the factory as a 38-40 and is now a 45 colt. Any information as far as maybe who engraved it or whose it could be or who made the grips would be greatly appreciated.
