Order number 57V4828 1/4 with a price of $ 29.90 is with cabinet and 57V4829 1/4 for $ 23 is without cabinet, mounted on a baffle board. Picture in catalog #162. See details and summaries about Sears catalogs etc. Interesting that the price (including tube!) drops within a few months (Fall & Winter 1930, Cat. #161) from $ 29.90 to $ 19.50 or chassis from $ 23 to $ 14.50. The chassis is offered in Catalog #162 on page 487 for $ 13.50 but the complete model is missing.
