What Chuck H notes above is true. It can be somewhat confusing as production and names of instruments keeps going. The Bozeman/Broadus, Montana connection also has the distinction of being home to Flatiron instruments purchased by Gibson and Sound to Earth by Weber (now made in Logan). Kalamazoo facilities made Heritage instruments. I have much respect for the Gibson Custom Shop but you have a classic on your hands.
Being lucky enough to be in Michigan, I take my vintage and new stuff up to Elderly Instruments. You may check them out at
http://www.elderly.com. While they have some more than competent luthiers at their disposal, I would probably more recommend Simon or start with George Gruhn at Gruhn Guitars. George literally wrote the book. See
http://www.gruhn.com. Both Elderly and Gruhn are in the business. I would liken these shops to Purdey and H&H. Simon I like to think is a Trevallion.
I am virtually certain that you need to have the piece looked at for stability but that the recommendation will be that it just needs to be played. Any of these places will be able to recommend ways to keep its environment at the proper humidity.
