- National/Valco serial numbers provide the easiest way to find the year for a particular instrument. Serial numbers courtesy of Bob Brozman and his book 'National Resonator Instruments', 1993. Serial Numbers 1927-1935.
- National Resophonic headstock serial numbers Hi I own a 1997 NRP Style O which I have had from new. Though there is a serial number inside the body there isn’t one on the neck / headstock.
Serial Numbers Office
Gruhn's Guide to Vintage Guitars indicates that the Resolectric was probably made after 1990, but that serial number doesn't correspond with what is listed in the book. The Estralita Deluxe was made after 2001. Contact National Resophonic Guitars directly for further information.

Comments | National built instruments for Sears and Roebuck only during 1931. These models are distinctive as made for Sears and Roebuck because the coverplate has five vented section instead of nine, and the serial number contains an ‘R’ – stamped on the top of the head. This example is in good working order, and sounds great with a warm bark. |
