" A love of old and rare Horns".
This phrase is particularly true of the love that American hornist have for rare horns
that have beloved acoustic qualifies. Restoration is the art that can as much as possible
return an old horn to it's original manufactured condition. During the life of one´s horn
all areas that are moved ( slides and valve rotors etc.) or touched
( Bell, first branch & mouthpipe etc.) will wear out. In considering restoration the player
must decide on two main points which are the financial cost and also how the horn will
resemble its original condition both cosmetically and acoustically.
Cosmetics and acoustics:
On many old horns the slides are completely worn out or tapered. There fore it is necessary
to remove all the outer tubes from the horn body and also the inner tubes from the valve slides.
After removal, new inner and outer slides are fitted to the restoration horn keeping the exact
slide centerlines that the original manufacture used. Any special decorative ferrules ( used at
the end of the outer tubes ) are carefully reproduced. Any and all slide crooks are replaced
using the same identical new part. ( exact centerlines and diameters again ). Any and all branches
are replaced using identical new parts.
At Atkinson Brass we have new molds that duplicate the exact branches used on Geyer and Kruspe
horns. Without these expensive new molds it is impossible to make duplicate new parts used on
these old horns. Especially the 5th and 6th branches on old Kruspe horns. We have also made new molds
for the two difficult Geyer branches that connect the thumb valve branch to the F tuning slide and the
first valve branch that connects to the F tuning slide (all one piece). It is by far better to
duplicate and replace the part exactly as the manufacture intended than to repair the part with
ugly soldered patches. Patches inhibit the acoustic performance of a branch and obviously do not
contribute to the cosmetic beauty of a horn.
Bell condition is another consideration. To acoustically restore the horn your bell must be in
acceptable condition. The bell must have enough metal left to give you years of playing enjoyment.
If your bell does not have the metal left for either acoustic and cosmetic satisfaction then you must
choose a bell that you consider its closest equal or better to replace your worn out bell.
At Atkinson Brass we make Bells, First branches and mouthpipes that can be used to restore
your horn to it's original condition as possible.
Rotor condition: is another consideration. Most old Geyer's, Schmidt's, Conn's and Kruspe's etc. have
severely worn valve rotors. As this point of age it is necessary to rebuild your rotors
using traditional plating techniques (see rotor repair) which can be very effective or install new
rotors in the horn that are made to original manufactures specifications.
Since Atkinson Brass manufactures horns we have the special machinery that can make rotors to
any manufactures specs. This duplication includes length, diameters, port size and counter
bores etc. Sometimes it is necessary to replace the worn outside valve casings as well.
If this happens we can duplicate these casings exactly both acoustically and cosmetically
including threading and knurling.
We have named just a few specialties that we possess in restoring old rare horns. Indeed there are too many advantages as to why you should have us do your restoration to list. Our company has done hundreds of rare and older model horns. However if one had to list the largest advantage as to why you should do your restoration with us it would be that like you we also love these old horns and in our family we own Geyer's, Knopf's, Kruspe's, Schmidt's and old Conn 8-D's. They are after all ones first love.
Horn body with original style Kruspe 5th and 6th branches
"This picture is of an A102B horn body in progress. Notice that this horn has the old style Kruspe 5th and 6th branches that are no longer made except by us. Many old Kruspe's need these branches replaced and with our new original branch's we can replace your old worn out branches with new branches and everyone will think they are original."|

" Rotors are machined or ground to exact tolerances to give the player smooth an dependable valve action."|
