This entire discussion is really very interesting.
When the Kansas City Police Department placed their order for 250 Magnums on July 26, 1939 they specifically stated “Baughman Quick Draw with plain ramp” for the Front sight…..
My REG 5008 was in the resulting shipment on September 7, 1939. When Dr. Jinks prepared the historical letter for my REG 5008 he stated “Baughman quick draw front sight on plain ramp”…….
I have been advised by Historical Foundation that the only additional factory documentation available for this shipment is the shipping invoice which makes no mention of the sights at all…….
But my REG 5008 was in fact shipped with Baughman QD front sight blade on a plain King ramp…….
So certainly by July 1939 the KCPD was aware of the King ramp base, and that is what they wanted setting under their Baughman QD blades.
Hate to revive an old thread but, Nitschke was my great grandfather. I recently started doing more research on him and came across this thread, pleasantly surprised. Thank you all for sharing your knowledge, I’m trying to find and consume it all!
Welcome to the forum! The FBI website has a historical section and you might try an FOI act request. The site below was started by the late Larry Wack, a retired agent, and has a lot of info on the early FBI. Best of luck and please keep us informed, especially if you find any S&Ws !
