I found recently this corroded pocket knife . It was marked FAG "Neptun"
with a Trident logo in it.Most probably german manufacture...how old?
Thanks for watching and HH.,

Thank you NHBenz,
This logo is from an electro cable manufacture factory.So probably
this pocket knife was intended to be a propaganda item . It looks to
be from the 1930s to the 1950s.
