It's probably the same thing as the ones Jeff refers to. Cleaned up, it
may be pretty decent.

Something like this
<http://cgi.ebay.com/Tele-Astranar-500mm-f8-Universal-mount-lens_W0QQitemZ250086370790QQihZ015QQcategoryZ707QQrdZ1QQcmdZViewItem?hash=item250086370790>?
Or this

Looks like the same thing is still being sold new under at least the
Opteka and Phoenix brand names

You probably need to do further disassembly. Lenses, esp. old, simple
ones, are generally assembled using rings that screw in and out using
spanner wrenches like these

One may sometimes get by with needle nose pliers, snap ring tools with
modified tips, etc.
