Your revolver almost certainly shipped from the factory in 1907 or 1908. In any of the books mentioned above, you have a 38 Military & Police Model 1905, 1st Change made in serial number range 73250 to around 120,000. By the original company literature it was called a 38 Military Model 1902.
Just to be clear, none of those books will list your revolver as a Model 1902. It seems that the author and the original factory documentation differ in their description. According to Roy and Bob, anything made on or after 1905 is a Model 1905. The company literature of the time shows that the round-butt stocks were called Model 1902 all the way up and until the company dropped the year of the model.
Here is a brief history of the model names given by the factory for this K frame revolver right up to WWII.
• 1899 to 1902 the K frame was named “Military Model 1899”
• 1902 to 1905 the K frame was named “Military Model 1902”
• 1899 to 1904 all K frames were round butt
• 1905 to ~1911 round butts were named Military Model 1902 by the factory
• 1905 to ~1911 square butts were named Military Model 1905
• ~1911 was first use of “Military & Police” and the terms Model 1905 Square Butt and Model 1902 Round Butt
• Starting ~1916 the year was dropped and the two models became the Military & Police “Round Butt” and “Square Butt”
• Late 1930s the company named these K frames as Military & Police, Round Butt and the Military & Police, Model K
