Please help me out. The one in the center is a purple CREB. The Postal on the right is also for comparison. What Style or index [number] is the WGM on the left? Answers could "bee" [010] Reg., [015] Grand Canyon, [020] Postal. If you can, please post a picture of all three different WGM's. The base dimension of mine is 3 1/8" and the height 4". This rules out the Postal style which the base is 2 15/16". Correct? The June 2005 article in C.J. states there are four separate molds each for the Postal and also the Western Union Style. ANSWER [010] Reg."Western Union" Style. Have been told by several collectors the Grand Canyon is not a Style, it's a mold variation of one of the two styles.
