You've come up trumps again, Ian. So L.J. Greenberg and G.E.Hyman were responsible for the sound bits. Is that right? But we still need to find out who invented the 'Major Morgan' idea. Have you any thoughts on that?

Good to see the packaging and now we know it was called the Electronic Organ.

Major Morgan was invented by Greg Hyman and Larry Greenberg of Hyman/Greenberg Associates. The Museum of Play says - ‘Fresh out of college, Hyman built customized electronic devices for advertising and public relations firms and for television game-show presentations. By 1974 Hyman had partnered with Larry Greenberg, a man he had met in television work. They started their own firm, Hyman/Greenberg Associates, and developed toy ideas to pitch to manufacturers. Because no manufacturers licensed any of their electronic toys for several years, the two inventors needed to keep “real jobs,” as Hyman described them. In 1977 the men’s luck improved. Creative Playthings manufactured the pair’s first toy, Little Maestro Piano Organ, and Milton Bradley signed Hyman and Greenberg to contracts that paid advances against future toy ideas. Finally, the two could turn to toy design full-time. Playskool introduced their first big success, Alphie the Robot, whose lights, sounds, music, action, and games helped youngsters learn letters, numbers, songs, and more. Additional card sets varied Alphie’s lessons and activities. Alphie went through seven versions; the latest arrived in 2010, just in time for kids who grew up with Alphie in the 1970s to purchase the new and improved Alphie for their own children. Hyman and Greenberg licensed 40 toys together before Greenberg passed away in 1992. Their inventions include Major Morgan the Electronic Organ, an electronic musical phone, a Win, Lose, or Draw game, and the Big Blaster Electronic Bike Horn. In the 1990s and after, Hyman continued inventing toys on his own or with other inventors.’ See -http://www.museumofplay.org/blog/play-stuff/2012/04/the-path-to-toy-invention-greg-hyman/

Brilliant, Ian. So all we need to find out now is which plastic was used to make it. Do you have views on that?

No. Not without being able to apply the Williamson test. That is, being able to touch it. This test is, of course, better performed by Colin Williamson himself.

Thanks, Ian. I'll ask the colleagues to take another look. We are as a team much better at materials than we were a few years ago.

Well - we've.had another look (and feel). We favour HIPS but are not confident. Would you be inclined to agree Ian, or not?

Can't tell without touching it.
