Classic & Vintage - 2 flat spoke nipple

I picked up a lot of spoke and nipples. Oddly most of the spokes are just over 3 inches long.
Most of the nipples have 2 flats. One of the boxes suggests it was packed in 1927. Of course I have no idea if the contents and the box started out life together. Anyway, I am curious if and when the transition from 2 flats to 4 flats on spokes occurred. Pictured is just one type of nipple. There are nipples 8mm long with 4 flats, large gauged nipples close to 30mm long with just 2 flats. All sorts of stuff inbetween, mostly with 2 flats. Having ruined many, many spoke nipples I don't have any trouble understanding why they went from 2 to 4 flats.

Ya, that is what I said. Or are you asking for pictures.

Alright, more pictures. Short spokes. Large spoke nipple. Wrong about the size.

Think Tricycle.. old full sized tricycles used 12" wheels with big hubs and 3 inch spokes. Today some go-carts use 3 inch spokes.

This may be what you have..

Um, no. I guess that helps with the age of mine. Mine are not nearly that old I would think.

Ya, I suppose. I was really thinking more about the spoke nipples. Just wondering how old. Maybe 50s...

That one is 1900. I just thought may be....
