longmvu ---- HEY, this is all great advice --- but if you haven't listened to any of it --- then quick, go get a hacksaw, and cut the leadpipe off, (below the mpc shank of course) -- after all, you really don't want to ruin a good mpc . . ONCE you cut the leadpipe off (and ruined a perfectly good trumpet), you can go to the dollar store or the cabinet and get some duct tape, electrical tape, and you can tape it back together for practice and playing it. ---------------NOW THAT IS A SOLUTION THAT NO ONE ELSE GAVE YOU!!!!
ps. if you followed this advice --you now have discovered -- YOU ARE REALLY A WOODWIND PLAYER --- so tape the horn back together -- Ebay it for some money, and go buy a clarinet --- YOU WILL BE A SUCCESSFUL WOODWIND PLAYER!!!
