Thanks to all for pointing me in the right direction.

Man, but those sure look like the Hy-Gain AV-640 except for the two 
traps. The stubs, and even insulators look almost identical to those on 
the AV-640. They probably aren't but the photos could be interchanged.  
The top hats are constructed differently and appear to be a bit more 
rugged than the dead soft aluminum ones on the Hy-Gain. The Hy-Gain is 
considerably less money too. OTOH the R8 and R6000 *appear* to have 
higher ratings, at least on 6.  I couldn't find any information on the 
matching network but it too (from the outside) appears to be much like 
the Hy-Gain. I did note that like the Hy-Gain they say not to mount it 
on the ground.  Hy-Gain says 5' above any conducting surface while 
Cushcraft..er...MFJ says 10'.
I'm not particularly fond of MFJ, but if they make a good 80-10 or 80-6 
comparable to the AV640 which is 40-6 (derated on 6) I'd be interested 
in using one for a backup antenna.
