Thank you, Russell. So, if I understood correctly, in 1936 only nitrocellulose varnish could be used with a small possibility of encountering shellac. Then another question - what can be the reaction to nitro solvent on shellac? On my console, at the point of contact with the solvent, the varnish partially dissolved and white spots appeared. I suspect it's shellac after all.
