I've been asked to restore a 1924 Gibson OType acoustic archtop. A photo of an identical instrument is here at http://lh5.ggpht.com/_mtgNjgX-tlY/TT_FY ... style0.jpg. I have got a pretty definite date on it due to design variations and numbers. (Although this model was discontinued in 1923, the slightly higher serial no. and FON number on this instrument suggest it may have been a late production in 1924).
The challenge is that while it is very playable -- its really in very good shape despite a couple of repairs here and there -- the saddle and bridge are missing altogether. I can see where the bridge was due to the marring of the finish where it sat. I can figure the hight it needs to be by taking a line off the nut and fretboard, which is amazingly true and in great condition. But what did it look like? How did it set up? I can't find any photo's any clearer than the one above. Any thoughts?
