Picked up my first mystery dial......Cool piece!
Wow. I've never seen Astro in such a dial, it looks like a colored marble. Very nice, just like the rest of the Z family. Keep it up !!!
Agreed, the dial is certainly what grabbed my attention. I have seen a similar dial in a green tone, but not this color.
Very early 70's. The Cosair and Guardian came with similar dials at that time too.
