Original style 7/16 External/Internal tooth washers

I'm looking for some 7/16 External/Internal tooth washers for a 45 MB restoration and my M38A1 restoration. They are the tooth washers that go on the steering box bolts of an M38A1. Anyone have some in your cans of hardware? I am not interested in the newer style and haven't yet found a newer washer in the original style. Picture below for reference. Thank you.

TJ,
I might be mis-understanding your post, but I have more than a few shiny new (Mil-Spec) part number MS45904-77 lock washers (NSN 5310-00-953-8628) that are identical to your photo --- except for the rust and they aren't mashed flat.

Measurements are here:

Let me know if interested.

Ron,

Do they look like the washers on the bottom or on the top?

Will these work?

TJ,
I'd have to say they look like the right side bottom, maybe a tad heavier, and the MS45904-77 are cadmium plated.

The other 3 that look used and somewhat flattened I found going through my hardware bin. I can't vouch that they're original washers, but they came off my M38. I only have the 3. I suppose I could've rinsed some grease off them before I took the photo.

Will take another if you like.

You're welcome to either, or both (plenty of the cad plated on hand). Let me know. Hope this helps!
