Happy to see this thread resurrected, again.
Here are my two bits (plus one) to contribute to the history.
1) Flora's five-screw Chiefs Special serial number 72
2) Photo of Flora and George Van Orden in front of their gun shop
(the gentleman on the left is Philip Roettinger, also a World War II
U.S. Marine who became a CIA ops officer after the war). To the
right is Flora's Berns-Martin holster.
3) Flora's four-screw Chiefs Special Airweight serial number 24295
(Rick Nahas photo)
4) Back stamp on Flora's holster
5) Photo of Flora and George with friend Nathan Hoffman at an
NRA convention (date unknown, but I would guess 1953). Flora
is holding her Airweight and wearing her Berns-Martin shoulder rig.
Great thanks to the three Smith & Wesson Collectors Association
members who sold these three pieces of history to me: Messers
Tom Horwedel, Rick Nahas, and John Witty.
