Joe, it seems that we both have paperweights!

Michael, thank you for the info on the lens and taking the trouble to find 
the pdf. If the focal length was a little longer then I would consider it 
to be useful for portraiture on 4x5. As it is, I can't really think of any 
useful purpose for it.

Cheers,
