  Order number 57LM 1660 1/4 with tubes for $ 18.50, cash only. See details and summaries about Sears catalogs etc. This model was manufactured for Sears by Colonial Radio Corp., Buffalo, NY (Sears Manufacturer Source Number Code 101).

  The chassis from this model is also used in model Silvertone 7056.

  Note: The 1933 Sears Catalog shows an illustration of the radio having just 2 knobs. However the parts list has a separate ON/OFF power switch listed and all existing known versions of this model have 3 knobs.  Thus it can be assumed that the 2 Knob Version was never produced. The 3 Knob version model page is here.
