That is an X E Ajaha cymbal. Made in Italy. That trademark belongs to Gretsch who registered the trademark some time prior to 1912 (Rob Cook, The Gretsch Drum Book, 2013:248) That is an early one, not 1970s. Could be anywhere in the 1920s to the 1940s or maybe later. The general pattern with these Italian cymbals is that they look like their Turkish cousins from the same production era. This one doesn't look 1970s in the least.

During some years Gretsch had their Ajaha cymbals manufactured by some members of the UFIP collective. Accordingly Ajaha appears on the UFIP list of stencil brands.

However, there is some evidence that in other years Gretsch had contracted their manufacture to other Italian manufacturers. Not every Italian cymbal is UFIP, and Tosco was always an independent manufacturer who were not part of the UFIP collective (later a limited liability company). The two main works on Italian cymbals are Luca Luciano Italian Vintage Drums and Cymbals 2012, and Hugo Pinksterboer, The Cymbal Book , 1992.

Pinksterboer mentions Ajaha on p172 under Tosco, but that would refer to later cymbals as Tosco only operated from 1974 - 1986 or so. Luciano also mentions Gretsch having their Ajaha cymbals made by Tosco (p124). Neither he nor Pinksterboer really go into the other Italian manufactures of Ajaha over the decades.
