I have a few decent sets of original S&W grips. I apologize in advance for the poor photography.
1979 NC State Highway Patrol 50th Anniversary Commemorative, Model 29-2
Model 27, no dash with "Coke" grips.
1937 Registered Magnum, REG-2269
Not original to the gun (Pre-Model 27, 5 inch) but they have beautiful grain.
Again, not original to the gun, but contemporary to it. Model 66-1
Not original to the gun, but again, contemporary to it. Combat Magnum
