Thanks Joe. I knew you had a couple styles so I did a search on Alphadrome and found the old thread. Your version of mine appears a little different in that it seems to have a scalloped border where mine does not, at least that's the way it looks in the pictures. I'm goint to mount mine on the ceiling, it may be a little less likely to get broken. There's still a boxed one of these on ebay, unfortunately it doesn't contain a date, I'm guessing 50's/early 60's.
