Dear friends:
Im using a cornet Bach 6 mpc with cornet to Trumpet adapter. I want to buy this mpc in the trumpet comfiguration. Bach cornet 6 have 26 throat and 24 backbore. Bach trumpet 6BM too, the question are this rims are supposed to be the same? Thanks

Sorry - all three rims have a different shape - check the Kanstul.com site to compare the outline of the rims. My lips tell me they are different in shape and in size too. Of course the 6B has a #7 backbore, 6BM a #24 backbore, while the 6 and 6c have #10 backbores. The good news is that the 6 is a pretty good trumpet mpc though on the dark side . I have several variations of throat and backbore. A stock 6 with the throat enlarged to #26 or #25 might be a good starting place since you are used to the more open cornet mouthpiece. Most larger stores can enlarge the throat for $10 or so. Your cornet adapter also gives the feel of a more open backbore so the regular trumpet backbore may be brighter sounding than you are used to. Of course a 6 with a standard throat but a #24 symphonic backbore would be the closest to your cornet combination - perhaps you could find someone locally to enlarge the throat a little at a time until you get a good match to your cornet combination. I have a 6 top with a haggstrom/parke #24 backbore (#26 throat) and a 6 with #24 throat and Osmun approximation of a Bach 24 backbore - both work pretty well on a.464 and a .460 trumpets and are similar to the cornet/adapter sound.

The problem its that here's no larger store with a complete side run of Bach Mouthpieces to try and discard. I like the 6 cornet rim but in the trumpet mouthpiece configuration. You tell that have variations. Are any of them identical to the cornet one?
