I started this particular thread, because on my 'new paradigm' post it was alleged that Condition One carry did not begin with Cooper and/or the late '60s. I was mighty surprised to discover that there could be anyone today who didn't know better. Here are a few more pics of the state of the art as it evolved into the late '60s:

Note that all 1911s are Condition Three except the Cooper Combat.
Notice, too, the crediting of Jeff Cooper in the Bianchi catalogue's description of the famous Model 45 "Cooper Combat"; the 'fly-off' strap is credited to Eldon Carl. It wasn't long ago that Cooper's personal Model 45 was auctioned off (I've a picture of it somewhere).
