I found another ad for the B39 from the June 1928 Electrical Merchandising magazine.  The scan is better than the one I found in Playthings magazine.  I also found another ad in Electrical Installation Jan 1929, Vol. 45, No. 1 on page 182.

No other hits outside 1928 / 1929 and the one for 1929 there wasn't anything past the Electrical Installation ad.
