Hi Fred,
I think they are hand made and maybe not that old. When we were trying to get the OS 40 SFR to run properly many of us (me included) hand built props just like that. Many of the hand made three blades were keyed and epoxied together from cut down props. I made a number of them from Rev-Up 13 X 5, 12 x 6, and 11 X 5 props. Many of the flyers used aluminum plates (washers) on each side of the prop hub. They were also drilled and tapped for 4-40 flat head bolts threw each blade. They worked pretty good and you really were bummed when you broke one lol. I'm sure glad we now have C/F props and about all we to do is repitch them, thanks you prop makers!!
Later,
Mikey
