Happy Birthday, mtngunr!
I like 5's as well (Just not as much as 3's). The neatest one I ever owned was a Bearcamp Special. The earliest one I ever owned was one from WWII. According to Gaddis, Bo didn't come out with a civilian version of his Model 1 until post WWII. However, several years ago some guy picked this up at the San Francisco Cow Palace gun show and put it up on e-bay:
He thought it was a 60's knife and I guess a lot of other people did as well as it went cheap. The primary "tells" it was WWII were the brass nut and washer and the stamp placement. The CJ Moore sheath was the icing.
Best,
Ron
PS: I was doing a random Randall search on the internet a while ago and ran across the 1911 forum. Those guys miss you a lot!
