No / in fact it is very clean and probably spent most of its life in the case. Older archtops from the 50s/60s sometimes have their bindings and guards made out of acetate material which is unstable, and has a tendency to decay over time. That's what happened here. The process also corroded the metal parts. |
Actually, the material was most likely nitrocellulose. It was common on older guitars. It is also called celluloid, and has had many uses over the years. It decays over time, and in doing so it off-gasses
nitric acid. The result is the crumbling and corrosion you had on your guitar. It was also used extensively for pocket knives, with the same results. It is also highly flammable.
A major use was for various film stocks. Many early motion pictures have been lost forever because the film itself has disintegrated.
