HI guys,
We all know the purpose of a foil bottom, used as a shield. My curiosity was why patterns, and thought these foils were used elsewhere in industry.

I think Ron's explanation works the best, that's what I was thinking. If the company found a cheap source for foil they would use it despite having a pattern on it.
I am just thinking what original use would the foil be? Placemat pieces? Maybe inserts for a gift box? Who knows? One of these days I'll see something with the same pattern on it from back in the day.

The two examples shown are factory issue pieces. They came from 2 seperate radios bought several years apart. Model 84 early and the later 84B.

Curiosity got the best of me, so I went down and removed the chassis from a future restore 37-84. The foil pattern was again differnet. Not in good shape, but this is a third pattern.

Audin, this throws out the crystal growth design theory There is nothing on the foil. If I pressed it down it would be flat.
Here's the latest, kind of cool woven efect.

So, the mystery continues. I just thought it would be an interesting thing to try and find out about.
Take care guys.
