Don's viewer lenses

Another post that got bounced yesterday...

This should be the last of them...

He said they were surplus Erfle eyepieces and 
I think he got them from Edmund maybe 20 or 
30 years ago.

BTW I'll post an added comment; I wasn't very
impressed with them. Don's very much an "in your
face" guy as far as how he likes his viewer lenses,
I think he would be most happy if you couldn't see
the mount edges at all. For me (and I wear glasses)
his lenses cut too much off the corners.
