Hot Rods Picked up a pair of no name slots

Found a pair of 15 x 3 1/2" aluminum slots on Craig's list. After some swapping and trading we both left happy. I'm sure the wheel experts will know at a glance, but who made them? And about how old do you suppose they are? Thanks!

 

First thought was Romeo Palamides, but weren't all of his mags unilug?

 

Ansen?

 

They could be Appliance....that would be my guess....good score!

 

,<<<<< those are the same ones I have on my avatar.

 

There are no other markings on them anywhere that I can find. I'm hoping the guru's will tell us all about them....
