The ones from Eagle Music are by Schaller and either made under license or knock-offs. The “real” ones are tho ones from Beacon.

My mate with the used ones lost one of the screws, ‘phoned Beacon Banjos and Bill himself answered.

Sorry for going off topic but I was once on the sound desk and Bill was playing his incredible version of Nola. Unusually, he made a mistake and stopped. Some wag in the audience shouted out “Good god, the man’s human!”
