Default 1940 Ford Cluster Gear Question

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

I'm no expert, but that doesn't look NOS to me. I could be wrong, though... it happened once before.

I've had quite a few NOS cluster gears and I do not see this particular cluster as NOS. It has chipping on the initial engagement part of some teeth and also you can see the wear on the sides of the teeth (where first gear starts sliding into the cluster).

I would agree that it doesn't look NOS. It does look in good useable condition, though. It's a classic 28 tooth cluster from a 16/28 gearset.

Thank you all for your valuable experience.
I realize more and more that I have a lot to learn.
The mix and matching of transmission parts is co critical.

Can someone please post a photo showing what the teeth of a NOS cluster gear
(like the one I posted) is suppose to look like when new?

THANK YOU V8: That photo is a big help. My gear is obviously used. I have two old transmissions I took apart and am trying to find out if any of the parts are worth saving or put in the recycle bin. I know the input shafts can be "saved' and used as clutch alignment tools.

Again, Thanks.

The cluster you have is very serviceable - especially if somebody takes a high-speed die-grinder and polishes the tips of the teeth in question. It is easy to do and I've done it on quite a few used clusters . . .

Thanks Bored & Stroked for that tip. I'll try and find a close up photo of the correct tooth configuration and give it a try. I do have a die grinder. If you happen to have a photo of one you have done, please post it. I do have 2 more cluster gears that need that "touching up" also.
Thanks. JIM
