My mum bought a secondhand alto saxophone a few years ago and now she wants me to sell it. I know nothing about saxophones and can't even find the make and model written anywhere on the instrument or on the case. This is the sax in its case: The front has a floral engraving: Close-ups of the pattern: The serial number is 8182: The neck, also engraved with serial no. 8182: Can anyone help? I have no idea how much to ask for this instrument, I can't tell if it's worth £50 or £500! Any advice appreciated.
