I liked the James Bond attache case I had that had a Lugar inside that had extensions you could attach to it to make it a rifle. I think I was the only kid in school that talked into the top of his pencil trying to be the Man from U.N.C.L.E.
I also had a light blue Fender Musicmaster and Vibro Champ Amp(pre-CBS blackface) that I loved and toted off to lessons with.
I didn't have a synth but my Dad made a Heath Kit solid state radio that didn't have an antenna so all it was good for was getting squelchy noises with. Wish I had that today! Very useful for my studio as a sound source.
