Hi George,

Well, given that they were an aftermarket item it might be hard to say. I can't, at this moment, recall the earliest ad that I have seen for them.

After loosing an original prop nut from my '14 (Grrr, gosh, shucks, and darn) I put them on every prop nut on my cars. As a period accessory I would feel free to use them on any car with prop nuts. Good luck with your project. Bill

They came from the factory on my 1907 Autocar.

Okay,..."prop nuts". Either everybody knows but me, or,.....nobody else wants to show their ignorance like me,.....so I'll ask. What are "prop nuts"? I Googled it and it said,...."propeller nuts". (???)

Harold -- They are the round nuts on the "top prop", which is the pivot point for top irons.

Harold-
They are the round headed "nuts" that thread on the top irons to hole the top sockets in place.

George is looking for a special locking washer that folds over the square part of the nut to keep it from turning, coming loose and falling off.

Here is an image from Mac's Catalog for the Model A. They are too small for Model T.

I have always heard them referred to as French locks. Buick (and perhaps other manufacturers) used them on their exhaust manifolds since lockwashers won't work.

I think Restoration Supply in Escondido, Cal. may sell them. It doesn't matter when they were used, if they keep your prop nuts from coming off!
