Block 30/32 did not originally have the beer cans on the LEFs. They were part of the ALR-56 mod (replacing ALR-69) that rolled out in 1993 and was fitted to the fleet over a period of years. So in ‘92 your jet would not yet have the beer cans, and maybe / maybe not in ‘93 or ‘94 or ???. You will have to check dated photos to confirm.
Here is a pic of 85-1455 dated June 1993 and the beer cans do not appear to be present.
The AirDoc book on USAFE Vipers covers the 86th during this time period. Pics of 1412, 1456, 1466, 1469, 1474 do not show the -56 antennas. It’s probably safe to say these jets didn’t get modded until they rotated back to the States and went to various ANG / Reserve units.
