The Zephyr ZR-930 came in at least four colors: red, "midnight blue", tan, and pale blue. The red and midnight blue examples that I have use NEC transistors, the pale blue example uses Hitachi transistors, and the tan example uses transistors marked "Zephyr" (probably made by TEN?)
One other difference here between the tan example and the other three is that those three are all marked "JAPAN" on their cabinet's back bottom corner whereas the tan example has only a tiny blank rectangular depression, indicating a transition between countries of manufacture of origin (just add the sticker when you decide). In his wonderful "Great Little Radios from GLOBAL & ZEPHYR" booklet, Eric Wrobbel has detailed the production transition of the ZR-930s from Japan to Hong Kong between c.1960 and c.1962.
