Bob, Thanks - I thought 1284 must have a smooth lid based on its other characteristics. I'll be sure you get a copy of the research results, but of course the best method is to subscribe to The Sound Box and have the benefit of 6 or 7 other articles (certainly more interesting than mine!) in each quarterly issue!? Just go to www.ca-phono.org to subscribe.? You won't be sorry - - it's the best publication in our hobby.? Rene Rondeau does a great job as Editor, and I hear that the next issue will have an article on early Edison/Keller coin-ops by Allen Koenigsberg, and an article on Sonora by Bob Baumbach (plus another half-dozen or so articles).? You won't be sorry.
Thanks again, Bob - - Best, George Paul
