T00O 1996 Principato di Seborga
I've checked my log book for the date and the operator gave the name "Claudio". He asked for QSLs via S50B and as there's no address noted in my log I assume that I would have sent my card out via the RSGB bureau here in England to S50B. His card arrived 15th May 1998, so only an 18 month turn round, which isn't bad. As a matter of interest I only worked one other station that day - 5A1A Abubakei in Libya but his card took almost 6 years to reach me.
