I have clarinet with serial number p0048746, I think , it is Selmer but not sure, because there is nothing only serial number. Is it Selmer clarinet with this serial?

I would speak to Boozey and Hawks.

Not sure about the serial #... but 'C' clarinets are not common.
They are slightly shorter (2" perhaps? ) than the far more common Bb clarinet.

Appears to be 1979, but I am only reading from the web page shown.

Hi Erica.

Conn/Selmer has a web page with dating for a number of their affiliate instruments, though it doesn't look to be complete.
Serial Numbers If it was lumped in with the Conn 'Reed Mouthpiece' Instruments (as opposed to cup mouthpiece, which I'd think of as more 'brass', then it'd look to be 1899. The Artley Flute list starts with a serial # of 10000 in 1952. There appear to be other people out there having difficulty using their charts, and the Customer service page on the website is mum about contacting them directly, and suggests calling a nearby dealer. The dealer page is at

The description makes it sound like an Omega Model, see for instance

Hoping that helps.., and Happy Holidays

Between $40 -75 or whatever someone is willing to pay

The Ambassador was their most successful student instrument. The serial number is usually on the back near the tenon joints. Olds Sons Serial Number Listings The link takes you to a list of their serial numbers and the dates manufactured.

Serial numbers used to be used to tell the age of instruments. It seems now with Yamaha they are used as a tracking number for accounts purposes.
