pangaea

I just bought a Cavalier trumpet on Ebay for so few dollars it's almost criminal--or perhaps that's all it was worth! In any event, I'm looking for some info.

I basically bought this horn so I could test out the whole "peashooter" feel...it's kind of an inexpensive dry run before I plunk down a bit more for a 40B vocabell or a New Era (horns I like admittedly JUST for the way they look).

So: I know the Cavalier is a Conn stencil. What I don't know is: how does one tell the bore size? there are no marks to indicate whether it's the Conn #1, #1 1/2, etc. I know from the ConnLoyalist and other net resources that it's either a 90B, 92B, or a few other model numbers in the 90s. But how is this determined? Also, the serial number does not seem to be in agreement w/ the published Conn serial numbers--this one is around 50,000, but I also know it was made between about 1930 and 1936, so something doesn't add up.

Finally, is this body essentially the same body used for the 40B and 58B? is my idea of trying out a Cavalier to see what these more expensive models feel like totally flawed?

thank in advance.
