I have a wonderful 10M that I am having a tough time fitting into a time line....The man that GAVE it to me played it in the Navy Dance Band. I THOUGHT he said in '46, but the #'s don't seem to match. I had it re padded and re corked, and all the springs replaced, as well as some corrosion repaired. This horn plays like a DREAM. No dents, and a very lovely petina. serial number reads as 348 278 L. There is the space in there........So...question #1. date of manufacture? #2. any guess at value with the given info? I appreciate any help.
