NSN (National Stock Number) 10W-272410

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 ‘standardized material items of supply’ as they have been recognized by all NATO countries including United States Department of Defense 

They are stored with us in original Colvern Ltd packaging and are unused and absolutely ‘as new’.  

Originally supplied to a large ‘Milspec’ type Co. these came to us as part of a lot of surplus stock, having been in storage for many years we have classified them as ‘new other’.

As can be seen from date stamps these were manufactured and sealed in their packaging way back in the mid 1950’s – see photographs, but as with all our products they come with a full guarantee to work perfectly. 

We Purchase Surplus Stock!!!

If you or your company has items similar to the above, or indeed any electronic components surplus to requirements, please contact us with details as we are keen to increase our stock profile.

 As many of our lines come in to us as surplus – sometimes from high end ‘Milspec’ type manufacturers we try to pass on our savings to our customers – often selling industrial grade or military spec components at a fraction of their original cost.
