hello everyone.
please I urgently need help as I want to find out the production yr for the trumpet I am just about to buy. have checked the Bach charts but they seem to be not working this time the serial is 791007 ML. what on earth could that mean? I am not an experienced trumpeteer and the seller claims the trumpet to be vintage :/ could that be a fact? please help. even drop just a line to my mailbox. mati_s@o2.pl

best regards and thanx for any help.
