[Dx-qsl] Question!

[Osten B Magnusson]

I'm helping a friend of mine getting QSL's for old QSO's.

Anyone out ther who knows:

Callsigns of today for  DM2AYC  1977
                                      Y43ZA       1981
                                      KR8DM     1972
                                      KR8IY        1972

The KR8-stations from Okinawa were Japanese, the
stations from USA used the KR6-prefix.
