Morning to you horn blowers I'm not really a trumpet or for that matter a brass player of any type....however I do buy and sell estates and all contents. Came across an original (in case) Martin Imperial Handcrafted trumpet. Everything seems to be in working condition except for the slides. All valves (or pistons) work fine except for the slide(s) which are stuck shut. Other than that, all numbers match, even the lac. is in VG+-EX condition. Should I simply sell it for nothing or take it to a place and have the slides worked on, then sell it for close to nothing? If this were the other "famous Martin Guitar", I'd like it better. Oh...forgot to mention, came with 3 old Martin mouth pieces. Any thoughts or just dump it at the August Allegan antique show?
