Hello
I am sorry. I did find this information for you. There is no way to restore what has happened, Celluloid can deteriorate over time. The biggest flaw in celluloid as it ages, the camphor molecules are ‘squeezed’ out of the mass due to the unsustainable pressure used in the production. The pressure causes the nitrocellulose molecules to bind back to each other or crystallize, and this results in the camphor molecules being shoved out of the material. Once exposed to the environment, camphor can undergo sublimation at room temperature, leaving the plastic as brittle nitrocellulose. Also, with exposure to excess heat, the nitrate groups can break off and expose nitrogen gases, such as nitrous oxide and nitric oxide, to the air.
There is no repair that will put the set back to original. The only thing to do is to keep this out of direct sunlight, and keep it in a low humidity area. Do not wash it with any harsh soaps, just dust with a damp cloth.
