Spike, I will try to answer your questions:
1. Do you have the manufacturers name of that cool plate frame?
I am not sure about the maufacturer (can't find the box)
2. How did you even know such a thing existed to even know that it had to be special ordered?
I was in Strauss flipping through their catalog looking for something else, and "bam" there it was.
3. Do you know if they have other styles?
Did not see different styles but It does come in powder coated black, which I should have got instead because the alluminum has iodized/tarnished over the winter due to salt on the roads.
