You have pictures of the Smith revolvers?
The first military and police hand ejector was the Model 1899, aka the Model 1899 Army-Navy Revolver.
The first several hundred were chambered only in .38 Long Colt in an attempt to grab the military's interest.
S&W was concurrently working on an improved cartridge, what would become the .38 Special, to hopefully address the shortcomings of the .38 Long Colt that were revealed in combat against the Moros in the Philippines. The first Model 1899s chambered in .38 S&W Special didn't hit the shelves until late 1900 or 1901.
