IC, CON, HDR, TR, VR, CHO, RN, RV, RLY, SW, LED and such are all
amateur inventions.
CR is still common. Is that supposed to be "controlled rectifier" (like in
SCR)?
It was "crystal rectifier", and D was "dynamotor". You don't see many
surface-mount dynamotors [1] any more, so lots of people have swiped D
for diodes.
These designators are the classic military ones.
