Super collection, Alan, thanks for sharing. The pic is great too. I may have to keep it on my desktop for a while so I can absorb it all - it's really great!
Jerry, Yours seems more like a blue version of a skunk, which is four white ribbons on black - a Rainbo. Paul's looks like an earlier six-ribbon NLR type.
I have always liked transparent red base glass and I would really like to see a wide variety of examples, so please, show them if you have them.
Thank You!
