[Milsurplus] FSN and NSN (nato)

[Miguel Bravo]

I picked up a pile of small radio items still wrapped in the navy supply
packs,  such as those high/W resistors with round terminals for clips, the
clips itself,  pots even packed inside a can, old capacitors, some are so
old that are called condenser, connectors, relays, transformers (main, AF
and RF).

Also, but not wrapped, there are valves, most JAN-CNU-1625 (VT-136) from
National union radio (feb 1944).

I have opened some but I don't like to open all those wrapped things and as
each item has its own FSN (USA federal stock number) if old or a NSN (NATO
stock number, not USA National stock number) if newer (some has both), did
somebody know of a URL where I can make a search for any or both numbers?. I
have been searching but opened a hundred pages with no luck and give up.
