Larry, The call out is for base material and refers to: "G"- glass fabric woven, "E"- non flame resistant epoxy, "062"- .062" thick, "C"- drum side out electrodeposited copper foil, "2/2"- double sided laminate with 2 oz. copper per square foot on each side. The call out comes from the old MIL-P-13949 base material specs. The current MIL spec is MIL-S-13949H and there is an IPC version, which I believe is still in the "Interim Final" circulation, IPC-4101. Hope this helps.
