Leather Specialities Company
makes excellent
leather
hand guards for
most (not tuba) brass instruments. Alas, no photos of
what you're getting; but I've seen a sample and they're
very nice. There are 99 - count 'em! - 99 different
models for horn, each made for a specific make and model
(e.g. "Conn 8D (East Lake) French Horn Hand Guard -
Leather - Black $19.78"). The site is young; perhaps
photos will follow later. They also make various bags
and pouches.

low-pressure playing. A valve inside the device opens
when too much pressure is used, allowing the air to
escape before it reaches the instrument. Adjustable."

Woodwind/Brasswind - Good price on the Konig and Meyer Horn Stand
($20) - they call it a
"multi-purpose instrument stand", but it suits the horn
much better than what they list as a 'French horn
stand.' Actually,
many guitar stands work just as well at about half the
price, such as this one offered by Musician's Friend.
The folks at Embouchures.com
offer a number of unusual but useful accessories, including
brass buzz pipes (a.k.a. "Fish Callers"), a "great practice
tool for staying in shape when on vacation" or when you
don't have your horn.
Tony Halstead sells something similar - his "Halstead Buzz-Buddy":

available from Thompson Editions, made by Gebr.
Alexander. Fits between mouthpiece and leadpipe; lets
air escape if maximum desired pressure is
exceeded.
Etymotic - makes Musicians Earplugs™ that
reduce sound levels 20 dB without distorting speech and
music. Get some. I said, “Get Some!”. Before it’s too
late.
From the web site: “A horn support device and leather guard in one. More ergonomic than the pinkie ring or flipper. Fits both Kruspe and Geyer wrap horns. Used by the Cleveland and Boston Symphony Orchestras. The Clebsch Strap comes with the leather strap and a metal screw mounting plate. The mounting plate should be installed by a brass repair technician.” $45 + $5 S+H. See the article on it by John Ericson.
