TromboneChat

I just acquired a used Warburton Oviedo 1G (a one piece). I am curious if anybody here knows information on the sizing of it? Warburton's own website http://www.warburton-usa.com/index.php/ ... outhpieces (the one-piece section) is either super confusing or I am not reading that chart properly. An inner diameter of 1.09 seems way too small to compare to a Schilke 60?

The 1.09" I.D. dimension is perhaps a typo.

From the (somewhat confusing) Warburton Website:

WARBURTON TROMBONE TOP SPECIFICATIONS
Model...Inside diameter...Available Cups
..1............1.140"...................B
..2............1.120"...................B
..3............1.100"...................B

APPROXIMATE DIAMETER REFERENCE
Warburton....Bach.....Schilke
...1.............-...........-
...2.............1..........60
...3.............1½....... 59

That's the standard line. The 1G is a one piece, so I assumed the dimensions would be different than the other stuff.
