Stephen Stills' NBNs
Gold-plated early National with custom NBN neck
In a January 1976 Guitar Player cover story article Stephen Stills is holding up this National in the mountain meadow photo, and it is half shown on the other story photo.
In a June 1979 International Musician and Recording World cover story Stills is playing the National on the cover photo. Here's the cover photo, scanned and cropped. The National is not mentioned in the article. It can be seen but not especially well in a couple of black and white photos in the article.
This resonator can also be seen on the back cover of the Stills album. Here's the album picture, scanned and cropped. Here's the same picture from the back of the Stills album songbook, scanned and cropped. Here's another photo of the National from the songbook.
NBN 5-string long neck banjo
In the January 1976 Guitar Player article Stills lists this banjo (mistakenly listed as N.B.M.). The banjo can be seen on the cover photo.
