[19Fordy]

I have a Ford cluster gear # 68-7113A "tagged as NOS". There is no sign of old gear oil or previous use. Tooth count is 28-24-18-14. There are no bushings in the "bore" and the internal bore measures 1.125 in. I know it has never been used but, I am wondering if the first gear tooth shape and configuration is suppose to look like photos below. Are the teeth shaped this way for ease of shifting into first gear? I am told this fits 1936-48 Ford.

The teeth do look the same as another used cluster gear I removed from a 40 transmission. In Mr. van pelt's book, I read about the "Square tooth and Diamond tooth" design changes in 1950 but didn't see any specific info. about "tooth shape" for earlier year gears.

Thank you for your continued help. Jim
