I've heard it, but I don't buy it (with respect to Brian). The CSO Yorks were made in 1929 or 1930, by the way. Jacobs was born in 1915, and attended Curtis at age 15, which makes his first time there in 1930. Donatelli already owned the York at that time. They were actually made soon after Pop Johnson became one of the owners of York after buying outu the York family in 1927.harold wrote:First time that I have heard this.

I've heard that the brass then used was not nearly as pure. I've heard that Pop Johnson walked hung brass sheets and whacked 'em to hear the ring. But I think it's like Strads, which are thought to be magic because of the age of the wood. It's not so--the difference is that Strads had all sorts of assymetries that nobody will build into a violin these days, except for those who have actually measured up real ones to duplicate them without trying to "update" the design.
I'll bet that the York magic, whatever that is, has to do with shape (including thickness, perhaps, though the magic hasn't faded with extreme buffing that must have materially changed the thickness) and, to a much lesser extent, how the brass is worked. But the best information I've seen is that Yorks used the same cartridge brass as everyone else, and that has nearly identical alloy proportions as modern yellow brass.
Nobody ever said York Masters had the York magic or were built or designed by Johnson. I would like to think that they used some of the York mandrels, but I think that lore has been pretty conclusively dispelled. York Masters are similar but not similar enough to have come from any of the same tooling. And they were never built to be big--the 6/4 Yorks of old were never represented in the York Master line. Big tubas like that were not the flavor of the month in the post-war period when Carl Fischer (who owned the York brand) hired B&M to make York Masters.
