Electronic double diode

A NATO Stock Number, or National Stock Number (NSN) as it is known in the US, is a 13-digit numeric code, identifying all the ‘standardised material items of supply’ as they have been recognised by all NATO countries including United States Department of Defense. 

Inside the box the valve itself is marked with the CV4007 Military no. and the M8212 commercial no.

These genuine Mullard Military grade valves were originally supplied to the Royal Air Force in 1982 they came to us as part of a lot of surplus stock. 
Having been in storage for some time we have classified them as ‘new other’.
In fact they are still in their original packaging and ‘as new’ in all respects. 
They are stored with us in individual boxes which are then multi boxed in 100’s (still with the military base address to which they were originally supplied)

The device measures 45mm long x 17mm diameter and has a 7 pin base.

The CV4007 and the commercial 5726 is a miniature all glass premium quality pair of signal diodes. The design was for detector service in wide band equipment. This would typically be RADAR. This premium rugged version was designed to be used in areas of shock and vibration such as aircraft equipment. The prototypes were the VX7129 and CV283 and the CV4007 is identical to the 5726, 6AL5W and 6097. The domestic version of these diodes was the 6AL5 and here the use was television video detector.
The two diodes are completely separate flat structures separated by a flat metal screen.
Identical to CV4007 = M8212 = 6AL5W = 6097  = 5726
