National Number Citation: National Vintage Serial Numbers 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.

From 1927 to 1935, Natonal used a different serial number system for each model. On single cone steel body models, the number is stamped on the top of the peghead. The single cone exception is the Style O, which are usually stamped into the body by the endpin. Serial number on a 1928 Style 1 roundneck tri-cone. On roundneck Tricone models, the serial number is stamped into the body by the endpin until serial number 2400. On squareneck Tricones, the serial number is stamped into the back of the metal neck near the peghead up until serial number 2400.

I'm having trouble decoding the serial number on my dobro. I'm wondering the year. Its a d style, wood body. Some codes i've seen. We tend to thing of National and NRP as the manufacturer of metal bodies biscuits but obviously yours is the exception. There are a couple of resonator specific.

On all Tricones after serial number 2400, the number is stamped at the top of the peghead. Note most of the serial numbers provided are from actual instruments. The year of manufacturer was deduced by evaluating catalog specs for the year. Square Neck Tricones, 1927-1934.
