Artillery 17" x 3.25" with 5 Lug on 5" Circle?

I was at a local yard today and hauled this rascal home. What the heck used these? I've got dozens of old wheel catalogs but don't find this one. From the pattern I'm guessing an early/mid '30s Olds, LaSalle, Pontiac maybe. But everything I have says they used 16"s. Anybody know for sure? Stu

 

Without a picture it's pretty much impossible to tell. Take a picture and post it on Chevybombs.com in the forum, they know all the artilleries in the book. I'm guessing it's late 30's Buick accessory wheel but it could be from a Packard or something more offbeat.

 

Shall do. Much appreciated. Stu
