Help Identifying a York

[tylerferris1213]

Hello everyone! I just picked up a peculiar York tuba today. It's a BBb with a .750 bore. Definitely looks to be a large 4/4 in size. Also, the receiver seems to be bigger than standard. I believe this rules it out from being a model 33. Any help in figuring out what model it is would be greatly appreciated! I plan on removing the 4th valve tubing and bottom bow for dent work and then putting it up for sale. It definitely has a York sound even with a few air leaks around the bottom bow!

If the picture isn't clear enough, the serial number is 105176

York loyalist says its a model 700.
It's a really helpful website.

Thanks! I need to check that out more often. Does the 700 model only have 3 valves?

It says 3 or 4 valves. How big is the bell?

It's at the shop right now. I'll measure it next time I get in.

Yep, looks like a 4v 700, or the GRBI Co. version thereof. Nice find.

And yes, the receiver is about the same size as what we call "Euro".

random nearly off-topic comment:

Those receivers - as well as receivers on old Holton 345 tubas - are true euro receivers, in contrast to many “fake euro“ receivers installed on tubas today (which are basically 1/4”-elongated standard receivers which accept standard shank mouthpieces, as long as a standard mouthpiece’s shank extends up far enough for the receiver to not bump on a shoulder).

Another random thought: measure the receiver taper. It may or may not be the old York proprietary taper, which is another reason a "standard" mouthpiece might wobble in the receiver. I used to have an old York tuba mouthpiece that had the tip chopped off decades before I had it so that it would fit in a Conn sousaphone receiver. It definitely had a different taper than "standard."

The original York "Al Tru" mouthpieces I've got have substantially larger shanks than any of the Euro shank mouthpieces I own (ie Dillon "L"), to the point where they don't even go in to the receiver.

I'd liken it to a "Kaiser" shank?

Encountering an original York receiver is a rarity because over time, most have been replaced to accommodate mouthpieces with "normal" size shanks.

I've seen two York large BBb receiver sizes

700 series tubas have what seems to be the same as a Euro

6/4 sized Yorks (and their monster sousaphone's bits) take a huge shank. Like @Yorkboy mentioned, there are York mouthpieces big enough to fit and work nicely. I just had one replated and it works really well on my 736.

It seems odd that the USN was likely engraved at manufacture [below the usual]. I wonder if the horn was some special spec just for the Navy?
