As far as I was led to believe GHN was the next available callsign when we applied for the call back in 1900 and frozen to death.? There were no vanity callsigns and you could only reserve a call if its issuing was imminent (CAR was long gone).? G8GHN was applied for when most of the new members got Amateur Sound licence B calls but of course these weren’t proper licences since you hadn’t done the one year CW only stint and been inspected by the Post Office Inspector (Mr Smith in S E London).
