Charles, Bill, John and Ron,
 I managed to fight the high winds in the bone yard and collect vents for
you.  They will need cleaning but all are in workable condition.  I have six
large vents with the big opening and also six smaller valves with the cone
in the center.  They flow less than the big ones.
 I have you in order of your response.  Please confirm your order and send
me a check for $60 ea.  That is $50 per valve and $10 freight.  I will need
your shipping address, too.
 Again, I have six large valves and six small.  That means there are only
enuf for the first three of you to recieve the larger valve.  Ron, do you
want to look at the small ones?  Check overhead on your next flight and
that's what you'll be getting, assuming the first three guys take the bigger
ones...
Thanks,
Walter Dodson
