1959 Aurora Mercedes 300SL Vibrator Original Mini Blueprint Prototype HMS Tjet .....Actual scale blueprint is approximately 6" x 8"....Marked Aurora in red on top and AU-338 to denote Aurora on bottom....These one-of-a-kind artifacts are part of the HMS Associates Archives, a large accumulation of prototypes, renderings & blueprints, publicity photos and other research material, and miscellaneous paper items that I purchased several years ago from an employee of this now defunct company.....In order to appreciate the importance of these pre-production pieces of toy history, a little background on the company that produced them is necessary......HMS Associates, founded in the late 1940's by three partners, was based in Willow Grove Pennsylvania. The company specialized in product development, taking their client's abstract ideas and converting them into "patterns", prototypes that could then be sent to tool companies who would copy them and make metal production molds. HMS performed services for a number of well-known toy/hobby companies, including Aurora, MPC, Ideal, Hasbro, Galoob, Kohner, and Remco. ...In 1994 the company was dissolved and all of it's assets sold, with the exception of the archives, purchased by me....an excellent addition to your collection....winning bidder pays shipping (est at $6)...Good Luck!
