When was my FWB150/300/300S made?

The FWB300 series of rifles really began in January 1963 with the introduction of the FWB150. This was followed by the Model 300 in 1969, and the Model 300S in 1972. Other variants include the Model 110 (lacking the recoilless mechanism), Model 300S Junior, Model 300S laufende scheibe, Model 300SU, and Model 300S Match L. You can see some photos of different models on the American Vintage Airguns site here.

The following is a list of serial numbers and the corresponding production dates. I did not compile this list myself; I suspect it originated with the experts on American Vintage Airguns.
