I was able to find a little info about these cymbals. 

"From 1968 to 1970, the Azco factory produced 'Zilco' cymbals. There were two types of Zilco's, one that was a Zildjian that didn't make it, a second, and the other was a thinner rolling that was done without any hammering at all, which cut costs."

I found a pair of 14" hats on ebay that look fine and likely cheap.

In general, are they any good?
