A MITE scale indeed, by B-T Company, Milwaukee Wi. Rates as of Jan 1, 1949. Light blue, as pictured. Some signs of use as in pics, still weighs accurately (checked by a modern kitchen scale). Materials listed on left (books, Mdse news, mags) and 'class' on the right, (air, mail, letters). Fascinating! Price is final adjustment; item will be removed if no bids.
