The car may be a Revell but I am not really sure. I have a Revell BRM body, same period, also slightly bulbous. I do not recognize the frome; most Revells came with an adjustable ladder frame, although some later RTR cars had a stamped frame. It could also be a Marx. Marx made cars and sets for Sears (Allstate tires???). It is not a Cox, Monogram, or Russkit. Neither is it a Strombecker which made a very accurate and desired Lotus 38.
