In the Book Jennings Slot Machines 1906 to 1990 by Richard Bueschel part one page 402 you will find a reproduction ad from the 1940 Billboard the ad ran June 8th and tells about the Jennings Modern Vendor. The machine vends a roll of mints with each nickel played, wins are registered on the dial for free plays. It has the standard chief mechanism, the ad doesn't show colors, wish I could have been more help, maybe someone out there can elaborate further.
