Oscar Adler baritone sax info
I found an Oscar Adler baritone sax, very old, rough shape but intriguing find. This horn has minimua keys, different let design and other odd aspects. I know there is little or no value but I think I will add it to my collection. Is there any way to guess the model, year or any info? Has the round small.stamped logo, serial number is 1715.
