Pete Seeger - banjo (I've had several but only an old Gem now)
Leadbelly - 12 string guitar (which I regret selling)
Mike Seeger - autoharp (an Oscar Schmit - my daughter is trying to learn it now)
Jean Ritchie - dulcimer (made in NZ in 1967/8)
Colin Ross - Northumbrian pipes (made by Ken Fisher but 'fettled' by Colin later)
Packie Byrne - tin whistle
The Tracey brothers (Wait a minim) - kalimba
That's all I can think of at the moment.
