I have just got hold of, more by accident than design, a SARBE BE301.
Obviously this model is one of the older SARBE models, RAF only?, and there appears to be very little information about it other than a quick mention in
https://www.radiomuseum.org/r/burnel...on_be_301.html and a Pathe newsreel dating from 1967
https://www.britishpathe.com/video/sarbe-beacon
Do you have or know anyone who can supply more information on this model?
In the 1967 newsreel they seem to mention that the product had saved lives for 8 years and that would suggest that it had been in production since 1959?
Looking at ink marks on other units for sale it certainly appears to have been in use up until the 80s?
Any help would be most appreciated.
