Shellac was used until the late 1920's, and during the '20's it started being phased out in favour of lacquer. The toning and cabinet colours are NOT stains. They are sprayed coats of tinted/toned lacquer.
As far as gloss vs matte goes, most high production radios (the average radio) were sprayed with a high gloss finish. These are not multi-coat piano gloss finishes. They are the glossy result of normal spray practices.
In most cases the "matte" finish we see today in original finishes is the result of oxidation, aging, and many decades of cleaning products applied to a finish that started out glossy.
