We have a case and on the case it says Lanier High School For Boys - Macon Georgia - 1924. Inside is a saxophone: The Martin Elkhart Ind. Near the base is Martin - 28993 - low pitch. As we look for model numbers we don't find any 5 digit model numbers. The name of the school is not a decal but imprinted in the top of the case. We'd like to sell this piece to someone who can appreciate it. What value and what year of make might this one be. We have the owners name which gives us no clues. The owner's name is on a tag with the key to the case. So the case is from 1924. It's condition is not that good suggesting that maybe the musical instrument might be from the same time period. Doubtful a later made saxophone would end up in a tattered case which surely belonged to the student. Thanks.
