1920'S Bakelite Snack Set???????????

Picked this up from an antique store that was going out of business.  The owner said that it's a 1920's Bakelite snack set that he got out of his grandmother's curio.  It's a set of 4, in perfect condition.  No chips, scratches, staining, or cracks.  They're kind of a marbled orange in color.  At their longest point, they are 10" x 9" x 1".  Three separate compartments for food.  I have beat up the internet to no end on these.  NO ONE can tell me anything about these.  The snack set is in the front of the picture.  HELP!!!!!!!!!!

Excellent
