Bjärton basses/cellos serial numbers

The numbers below are rough estimates only, based on the very limited information currently available to us.
Please help making this site more accurate and complete by sending us serial numbers and photos of your instrument
or any other information that you might have access to.


1946 - ca 1958
1-4 digits hand written on the label or 4 digits stamped into the neck heel.

When production began in 1946, the serial number and year was written on a label, presumably starting with serial number 1.
Later, from around mid 1954, the serial number was stamped into the neck heel.

When the guitar/mandolin production started in 1952, the first guitar received serial number 1001 stamped into the top edge of the headstock.
It is not known how many basses/cellos had been built at that time (the closest currently known serial number is 940, dated 1952.

According to a recent interview with former factory worker Olle Tornerefeldt, after a fire in the factory on April 29, 1954, the same
serial number series was used for all instruments. This suggests that before mid 1954, there were two separate series used:
One for basses/cellos, with the serial number hand written on a label (1946-mid 1954), and one for guitars/mandolins,
with the serial number stamped into the top edge of the headstock (1952-mid 1954).
After that, the same serial number series was used for all instruments, with all receiving stamped numbers.

However, please bear in mind that this is only our current theory, and more examples of basses/cellos
needs to surface before we can get a clearer understanding of their serial numbers.

Until more examples turns up, here's a rough guide:
