Fwd: [Drake] T-4XB

[Garey Barrell]

The Color Coded crystals came about during the R-4A, right around the 
same time the receiver design changed over from the 13 tube version to 
the 11 tube version, "officially" at receiver serial number 4054, 
8/25/66.  This would have been around s/n 12000 for the T-4X.
