Notes:
Both Stethotracer ST-111 kits I have are in plastic boxes (see photo above). The pieces are held in place with elastic cords and accessories are in a plastic bag underneath. Both kits contained a layer of gray foam which has disintegrated over the years.

Literature in the first kit contained what I assume to be the original address of Littell Road or 56 Route 10, Hanover NJ. The second kit in some instances had the Hanover address crossed out and a new address of 95 Brewery Road, New City, NY printed or stamped on it. A 1974 catalog I have is printed with 325 Broad St., Bridgeport, Conn. crossed out and ink stamped with the New City, NY address. I also have a packing slip for a Mosquito dated 7/11/1962 using PO Box 323 Hanover NJ.
