Edison Crank ID Help

[Crank_it_up]

I have two similar cranks that I just noticed are not identical. The width of the “S” at the top is about ⅝” on one and ¾” on the other. Both have an overall length of 3” and a little over 3-¼” overall throw. If measuring the throw on center they are closer to 3”. Note the peened end of the knob are 2 separate methods and the knobs are slightly different. I think they’re both original but I want to see if I’m missing something.
Thanks, Joe

Hi Joe- A few years ago, I asked the same question-- I noticed that I had cranks that were of different widths. I think the general thought is that the wider crank was for the early Home and the slightly narrower one was for the Standard. But no one had a definitive thought at that time.

In my pictures, the three to the left are the narrower cranks. I also have one with a hole in the back...far right in picture. So many mysteries still to be solved

Brad, thanks for the info. I just found another one and it has the narrower end and the knob crimp like the other. So, 3 cranks all unique.
