Technical No Name Headlights???

He you all, a friend of mine bought my 34 Ford Pickup project a few years ago and finished it pretty quick. He did not use the lights I found at a swapmeet and instead went with Guide 682 lights. Do any of you know who made these? There are no markings on it except SAE. They are not cone shaped like the 682s. They are flat like a skillet on the back side. Unique and I have never seen another pair like these since. I think he may want to sell them but not sure yet. If you all know who made them, or what they went on, please let me know.
Thanks

 

Show the mounting bracket on the bottom, and the way the ring is attached.

 

I don't have access to the lights but if I remember they were just like the Guide type. I'll see if I can get a photo tomorrow.

 

Here are some more photos of the headlight buckets to see if someone came figure out who made them or what they were used on.

 

If I had to commit to guess, I'd look toward a commercial large hauler

 

Pretty sure the screw tab ring attachment is not Guide/BLC. But the upper bulb housing sure has their style.

 

Why would it matter what they came from? If a 7" seal beam fits, use them.

 

Some Guide buckets have the name stamped into the bucket instead of tags rivoted on. Look close at the rear center

 

The owner is not on the HAMB but plans to sell them probably on Market Place, therefore wants to describe them the best he can.

 

I'll have him check it out.
Thanks
