[Boatanchors] Diode color coding

[Duane Fischer, W8DBF]

John,

I am not questioning your statements John, just wondering about the dates. I 
was blinded in October 1964 when I was shot, I do not remember seeing the 
color codes on diodes. Did I simply miss them or perhaps did they occur 
after I was blinded?
