Very Tentative bump on this, not particularly looking to sell but the possibility is here if someone wants to discuss it.
Second only to pre war Martins this D28 was made in January 1964 and predates the move to the new factory. As a result this D28 has the same spec as most D28s thoughout the fifties. It’s in fantastic condition cosmetically (bar the the wear on back of neck and buckle rash on back of the body) and more importantly structurally. The bridge/saddle have been changed as has the nut I believe as well as a washer on one of the tuning pegs. All else original.
