KA3HMS/KH3 - QSLs were to be sent to KA3HMS, but he is listed on QRZ as an SK. I'm willing to bet the logs no longer exist
WA1GIR/KH3 -Also appeared to be via his home call, however, his licensed is listed as expired. That said, he might still be with us. I found an old QSL on ClubLog with his address: 6 Ponderosa Dr Colchester, VT 05446.
Heck, I managed to snag a QSL from a former KZ5 op, who IIRC, is no longer licensed stateside, 27 years after the QSO. So, it can't hurt to try.
