Many thanks for the research. I didn't buy the trumpet for resale - just looking for a decent instrument to hack around at home. I had some trouble with the Nirschl 3C and 3E mouthpieces so I picked up a Bach 7C mouthpiece which I used to use 100 years ago as a student and it made a big difference in sound and range. If I give up the trumpet again I'll bring it into my local school band department and donate it to a worthy young student. Meant to up load the picture of the bell so here it is.
