Hello Fred, yes it had me beat for a minute. I call it the ancestor of the QR skewer, which most people will object to. Plus it's not really true. As per pics, the spindle is flatted one side (the other side holds the "nut" with that little swrew and 4 holes and is standard round): you move the simplex lever up or down to screw or unscrew. In effect, it's a safe, quick tightening/locking mech. Maybe the experts can help? I say 40's.
Sadly, I don't think I'll be posting much again, my "tongue in cheek" style has earned me hate mail I just don't need.
The only satisfaction I get from hatemail is pasting a standard reply as follows: "Thank you for taking the time to write to me, I really appreciate your mail. I always reply to inbox mail. Unfortunately, I have put you on the spam list so you went get anywhere near my inbox again. I now have some work to do, so thank you again for writing, and have a nice day"
Nick, What is that Simplex thing? It looks like some sort of quick release, using a different design than the one that is now so familiar to us all. Is that what it really is? Fred Rednor - Arlington, Virginia (USA)
