Found this guy in my office today. It's a long story, but needless to say it's probably relatively old. It's a Beattie Intenscreen for "Calumet 540 4x5 with grid".
Is this guy worth keeping? Is it worth anything? At some point, I'd love to get into 4x5 photography, but it will be a while. Should I keep this around? Does anybody want it?
It will work in any 4x5" camera that it will fit. IIRC, Sinar and Linhof screens, and others too, are exactly 4x5", other makes have slight variations.
