Nice CSO York Photo

Great Picture of Gene Pokorny with the CSO York.


I believe that is the same photo that The Brass Bow had on their website showing one of their clients. He is holding one of the CSO Yorks.Liberty Mo wrote:Sorry, the rest of the post got cut off by the photo.
Is this the CSO York or is it a Yorkbrunner? I thought that he owned a Hirshbrunner version, but the photo had a caption stating that the horn was valued at $25,000? Can anyone clarify?
Wondering if there are any good photos of these mysterious CSO Yorks available?

I should have all the spit valves removed. I never use them. It is all dumping, all the time.PhilW. wrote:Plus, another way to easily tell is that the Hirsbrunner has spit valves on the 4th and main tubing, whereas the York only has a spit valve on the main tube.
A big part of what you are missing is that there are two York 6/4 CC's. The Hirsbrunner is a copy of one and the Nirschl is a copy of another, I believe #1 and #2 respectively.Liberty Mo wrote:If someone wanted to make an exact copy of the CSO Yorks, and assuming they had access to the horns as apparently Hirsbrunner and others did, why are there differences? Were the copies supposed to be improvements made to the CSO York design?
I would figure that exact measurements could be taken, a metallurgist could figure out the composition with relative ease, and a true EXACT copy could be made, minus the internal buildup of human particles of course. Any object made of metal, no matter how complicated, could presumably be created in its exact form if enough RD is devoted to it.
I am just curious. Did Hirsbrunner set out to make an exact copy or was the CSO York meant to be a starting point and then improved upon. This question would also apply to the Nirschel, Meinl Weston, and Yamaha versions too. Are these exact copies?
If players wanted to own the CSO York, and presumably this fueled the demand for the copies and development of copies, then why didn't someone build the CSO York?
Just Curious?

Hirsbrunner is the copy of York #1 and the Nirschl is a copy of #2.Liberty Mo wrote: I am aware that there are two Yorks, but was not aware that the current copies used both. Do some of the copies use both incorporated into one design or are the a copy of one or the other?
Apparently Nirschl did, as others have said. And Yamaha. Holton is probably closer than many think, at least in terms of manufacturing methods, because it's likely that Holton and York used the same tooling for many of the big branches during parts of their histories, at least.Liberty Mo wrote:If players wanted to own the CSO York, and presumably this fueled the demand for the copies and development of copies, then why didn't someone build the CSO York?
I think I speak for a good number of TubeNetizens when I say " that is just cruel to leave us hanging like that"bloke "who won't comment on this further in a p.m., either, so forget it"
