from my email yesterday.

Hi, I was wondering if someone can help. I have a 1930's V.Back, made in NY, serial number 1567, Model 7, but I am unable to determine bore size. No one appears to have alot of information on trumpets 1930-1933. Can you help?

I would contact Conn Selmer in Elkhart and politely request the shop card for your trumpet. That should have the original configuration of your trumpet. The other way to commonly measurethe bore, would be to remove the second valve slide, and measure the diameter of the tubing. My guess would be eother a M, or ML bore.
