Picked this up for 10 bucks at an auction today along with a 78H.

It has a 7 inch bell that seems to be almost entirely copper. Similar color to Conn Coprion but SUPER heavy. Yellow brass outers and two very heavy large hexagonal nickel counter weights.

Says "bellaire Made in USA" on the bell. Seems sort of similar in build to some old bueschers I have seen but build quality is worse. I"m sure this is some junk but I am super curious.

Not sure how to add pics but will if I can!

You need to make a couple more posts before you can upload images.

I have a Bellaire 41 trombone mouthpiece (tiny thing, flat rim). Didn't know they made trombones as well.
