Early Quick change help, Please

[Pothole Jim]

I got these QC gears in a box of random gear sets. I have put the sets together and identified all of them except this last set. What do these gears fit? I have never seen a QC that had a 4 spline shaft. Any help would be appreciated.

May not be meant for an automotive quickchange application. Probably for some other industrial use, and got mixed in there because it "looked" the same.

I can't imagine why a quickchange manufacturer would respline the Ford pinion with a new pattern, or attempt to make his own pinion.

Unless they are really small, and are maybe some Crosley-bred type quickchange.

Thanks for the input, I do believe that these are for a QC and not some industrial gears, They have the same Center to center distance as every other QC gear set I have.

Crosley type rear? Never heard of such an animal.

Anymore thoughts? Help would be greatly appreciated.
