I have searched. That's where the, "I have read" part in my other post comes from. I know how to use Google too.
Much of the information I've able to find is muddied with speculation and assumptions and is outright contradictory with other sites. It's hard to tell the wheat from the chaff. Hence the question asking for clarification. It may be old news to you, but confusion remains for those of us just coming to appreciate the world of Mosrite guitars.
But, thank you so much for your ever so helpful post.
