I think my son has a clarinet Selmer series 9* (with star), but we do not know how old is this clarinet. Clarinet has U-6780 mark. Can anybody tell me how can we find the year of make?

thanx

Looks like it's from the mid-60's. I used to have a Series 9, and, like an idiot, I sold it in high school for cash. If you ever want to sell it, please let me know!
