Hi Rick. Just joined. Looks like I also own the same model Dolnet. I think it’s a Bel Air, it has a letter at the end of the serial number and the diamond at the bell Love her. I bought this sax 28 years ago and have only just picked it up again. I’m rusty, luckily she isn’t. There is a little rattle and tuning isn’t quite there but it might just be me. Rather excited to see another one.
