[Antennas] Chicken band antenna for 10M

Hi All,
I've been offered the base antenna and push-up pole from the estate of a
CBer here in the mobile home park (free). I won't even have to take it down
as the "Park handyman" is going to do that.
It appears to be similar to the "Ringo" line of antennas, a tall (5/8ths
wave?) stick of aluminum with a small circular ring of aluminum tubing at
the base or feed-point, perhaps 12 inches in diameter. I figured that I
would disassemble it, thoroughly clean and polish the aluminum elements and
install it to augment my "antenna farm". (roof mounted Butternut HF-2V
vertical for 75/40M, Alpha Delta DX-EE fan dipole for 40-10M and inverted
Vee's for 20 & 15 M). It might be very handy when 10M finally opens up
again.
QUESTIONS:
1. How hard will it be to "retune" this for 10M? It appears that I could
telescope the aluminum tubing down some to shorten it, but what about that
aluminum ring? How do you tune that?
2. It would be placed roughly 30-36 feet from the Butternut HF-2V and
perhaps 15 feet from the push-up pole that supports one end of the DX-EE and
the center of the Inverted Vee's. I suspect that this will affect it's
tuning/pattern somewhat, but is it likely to cause problems to the HF-2V?
3. Apparently this antenna requires no groundplane, the roof is sheet-metal
and I figured on mounting the antenna just 1-2 feet above the roof-line. Is
that likely to cause a problem with this "Ringo style" antenna?
4. I call it a "Ringo Style" since I really don't know who made it. I
haven't been able to get close enough to it to examine it yet, but is this
style of antenna worth putting up? I figured on using it when the 10M band
opens up (come-on spots :) and perhaps even put up a 10M beacon if I can
find an old CB radio to convert.
