artillery wheel hubcap clips

I have a set of artillery wheels that I'm preparing to paint for my 37 D-2. A couple of the wheels are missing the hubcap clips. Anyone know of a place where I can get replacements?
Thanks in advance

Since all the IHC steel wheel centers on the light duty stuff look the same to me (see picture) I suspect any factory IHC steel half-ton wheel up into the 60s will have the clips you are looking for.

I thought the clips where only on the Canadian Wheels?

Now I gotta go look...

I don't think I'd go so far as to say they all had clips. The wheels for my '51 L didn't have retention clips.
Just a guess, but a phone call to mfgs. (like Wheelsmith, Vintage Wheels, etc.) that make the reproduction artillery wheels could provide a lead. Otherwise, word of mouth or a scrap yard.

You're right...later ones had the little knobs. Oops!
Still don't think they'd be hard to find. At least on this site.
