I was cleaning out my files of softball line up cards, old slot business files and art work from when my son was in kindergarten, he is now 35, and I came across these emails with the below pictures.
The email was from 2013 from Paulo Vogel. A seven-band external resistor with a funky handle and a trigger with a huge curved hook on it. Then a couple other electronic models. Just thought it would be interesting to post.
