Manufactured by famous radio company Marconi - to exacting military specifications - in 1960, whether you are a specific collector of Crystals or simply a collector of beautiful things, these are a real find.
The slender glass envelope which contains delicate precision engineering and a square plate of gold plated quartz make these early examples of Crystal frequency standards exquisite to look at.
Crystal oscillators revolutionized electronics, offering an important ultra stable time clock which all radios and computers from the very earliest require. The fact that these are from Marconi only add to their appeal and will make an interesting conversation piece in any art collection.
These haven't seen the light of day for ages !
