Thank you both very much.
Ken, I did in fact send an email to Case (at the link you provided), and one to the Case Collectors Club. I also posted this same question on Blade Forums.
All of these attempts were around 2-3 weeks ago.
No response from either email, and 100 something views on BF, and still no answers/replies.
One evening I spent around 6-7 hours researching on the net, and I also have spent days scouring dozens of books on Google Books. The earliest I could find was in the 1950's but that same author listed it as being used many time before with no mention of the reason or earliest use..
This is one of those OCD things that will drive me nuts, until I find out.
Jerry, Thank you for the link to the instructions. I kept trying different ways to post images until I had to beat my keyboard into confetti.
I love my NEW keyboard tho so it turned out well. My next stop is the instructional threads. Can't afford another keyboard...
