I own an original 1973 DOBRO. It was a prototype for a line of “Buck Owens” DOBROS. I bought it at the Factory in Long Beach Ca. It is a round neck, steel body, with douolian biscuit cone. Its SN is 0266. I think DOBRO went on to offer this style for a couple of years. Does anyone know anything about this model? I have never seen another one.
