Vintage Slotted Mag ID Help

[suthernboy]

We all have certain days we will always remember. For me: the day I got my driver's license, the night I met my wife, the day my daughter was born, 9-11, and now....the day I got my first set of Aluminum Slotted Dish mags!

Was working up in PA this week and had a chance to stop by fellow member "vintage bronco" Barry's place in MD. Great guy, true-blue Ford guy. Has a bunch of parts listed in the for sale section. I got this set of slots from him, and a couple of small parts for the Bronco, and then he must have used some hypnotic trick or something 'cuz I also left with a nice vintage FE alum intake (that I didn't even know I wanted!). If anybody is considering any of his parts they are all in great condition. He's a Bronco guy (of course) and he also restores vintage Kawasaki's, factory Rotunda and Ford tachs, and has a Beee-Yooo-Tiful triple-black '65 Comet Cyclone out back.

Barry didn't know the brand of these wheels, maybe someone out there knows because they have a similar set. Cast on the inner edge is "15 x 7 EWC - U1" and "MAX WHEEL LOAD 1580 LBS." That's all I can see no name or logo. They are the type that the center cap would slip in from behind, not drilled for mounting screws. Center hole is 3-3/4 from the front side. Here's a few pics, any help appreciated.

Eaton wheel company
Eagle wheel company
Just guessing.
If they are old they are likely magnesium and not aluminum.

Thanks Bronconut I'll do some research on those brands.....it doesn't make that much difference I suppose, I just like to know what I got.

Is there some easy way to tell if they are magnesium or aluminum? I mean. without setting them on fire? That may help in dating them. (I did the "magnet test" and have confirmed they are not ferrous )

Magnesium will react to vinegar(or another acid) and fizz like hydrogen peroxide. Aluminum will not.

So I could just turn one over and fill one of the small casting cavities on the back side with vinegar and watch for the fizz? Then clean it off and flush with water I suppose....

I would clean an area up with a scotchbrite and test there. The oxidation may react to the vinegar as well which wouldn't give you a definitive answer.

Great! Thanks I'll try that. g
