Sansone imported fairly well thought of horns and trumpets. Judging from what you found, other stuff, too. Best I can suggest is to put some playdough into the mpc (maybe use a cooking oil as a release agent first) and then use a digital caliper to measure the ID, depth, throat, etc. Then you'd have a better idea of the parameters. Ditto for your other find.
