Outstanding acquisitions! Now you need to add Joe Friday's S&W 2" Model 10 from the second "Dragnet" (1967) series with Bill Gannon (Harry Morgan). Gannon used a S&W 4" Model 15 (per IMFDB). I think in the past that Forum members determined that Broderick Crawford (Dan Matthews, "Highway Patrol (late 1950s)) also used a S&W 2" Model 10. Congratulations, enjoy!
