Just look at this advert from 1941 from Furzehill.
Just look at this device incorporated into an advertisement that shows the precision delivery of a bomb down the chimney of a Boche factory, stirring stuff... but look close, for doesn't the contraption dangling from the (Halifax?) bomber remind you of something?....... what, not even the drop lead from a R1155/A1134 Lancaster/Halifax intercom system - it does to me and here's a photo to remind you.
I reckon their marketing person was a member of a Lanc. crew to have drawn this advertisement in 1941 - what do you think?
For those who are not familiar with this company, Furzehill Laboratories of Boreham Wood Hertfordshire, incorporated on 19th August 1939, were manufacturers of Electronic Laboratory Equipment including Oscilloscopes, Oscillators, Attenuators, Valve Voltmeters, Output Meters, Frequency Standards, etc. Industrial Equipment including Watch and Clock Timers, Magnetic Amplifiers, Power Supplies and Servo Control Mechanisms. Their wartime proliferation was overseen by J.H. Reyner as Managing Director until his retirement in 1964. He is famous as an author of radio books - some of which we have on offer here but you may not be aware that he penned a volume on Psionic Medicine - this term comes from psi ('psyche') and the -onics from electronics and there are a few people I have come across who would benefit from psionic treatment in the form of Electro Convulsive Shock Therapy!!!!!!!!!
Furzehill left one heck of a legacy for when their laboratory block was demolished as their roof was made in 1951 from that wonder material asbestos cement and little did we know what that meant at the time!
