I know Rick Denney has a comparison on his website where he tried to put a drawing of a York up against his York-Master. So I figured I would do it for real and place my York-Master side by side with this old York and see how they match up. So I put the front facing bell on my Y-M and lined them up for photos. The bells are almost identical, the wrap of body of the York is a little taller and narrower and it is noticabily lighter by weight. The valves are also larger in diameter, in fact when I removed one from each, the bottom of the Y-M valve would slip inside the bottom of the York valve. The York valves are also aligned slightly more horizontal (less vertical). The valve tubing for the York a tiny bit less in diameter than the Y-M, maybe a .748 vs. a .750 bore. The plumbing of the valve tubing is extremely similar.
Below are side by side photos so you cansee for yourself. Enjoy!





Now, with Dan so overloaded with tubas in his shop and about a three year waiting list, I wonder if I could talk Bloke or Lee Stoffer into taking a look at it? All the valves move OK except #4, it's stuck but most of the slides move nicely. In fact the valve tubing looks to be in excellent condition. Maybe find an upright York bell to swap into it? I got it real cheap, so putting money into it will be no problem. Only Dan will have to finish my Holton before I get too carried away...
