National serial numbers

Steve P · Post by **Steve P** » 9 Oct 1999 11:23 am

Is there an online resource that indexes the serial number on National / Supro / Valco guitars to their date of manufacture ?

I don't know about anything on-line, Steve, but if you want to date a National resonator guitar, look in the back of Bob Brozman's book on Nationals. If you're looking for something on, say, a 1960 Supro resoglass I think you are out of luck. Brozman does a good job of covering a lot of the pre-war resos, though. - Dave

Just to clarify my interest: I'm trying to determine age of several lap steels manufactured as either National or Supro brands.

Any online (or other) resources for dating these lap steels ?

thanks

Steve,
One place to look is the "Gruhn's Guide to Vintage Guitars". There's a serial number breakdown in the National/Valco section. Holler if you do find an online guide.
