Series II baritone - serial number?

[mpiader]

I know that this is a fairly common that is asked in these threads, but I recently bought a beautiful Selmer Series II baritone saxophone for $5000 from some guy in Texas.

The serial number is #645873 and I'm trying to get a feel for when it was made. I'm guessing that it's probably about a 2005, but I have no way of knowing for sure.

Does you know if someone has posted an updated Selmer serial number reference chart that goes beyond 1992?

I also recently bought a used Series III alto at #666315, which the original owner said it bought new in 2006.

I'll just go ahead and answer my own question, since I did a little more research:

If you look up the 'Selmer Serials' facebook group, you can find a rough approximation of when your modern Selmer saxophone was made.

It appears that my baritone was manufactured in early 2004, and that the alto was completed in late 2004.
