ID a air rifle

[WebleyWombler]

Hi Guys,
the motif “BSA” embossed on the wooden stock.
Is there any way to establish what model and year of manufacture from the serial number?
Thanks for any input,
Brian.

It is either a pre war 'breakdown ' pattern ( stock finishes just behind the trigger guard)

Or

A post war ' Cadet' model ( stock finishes near the breech and runs under the air cylinder)
