Not sure all the info got through so I will give it a other go.When I brought the knife the Lester handle was well dried out and had shrunk quite a lot so these photos ime sending are after treating it with some neatsfoot oil. Like I was saying the blade is just over 5"long ,no markings on the blade and no markings on the screw on pomel..been doing some research and know it's a pilots servival knife ,what I don't know is Wetheringsett is an early American knife or if it's been made in japan or China which would then make it more like late 70,s I think.ime hoping some friend over there in america could help.ive only been collecting knives for about six months but it really gives me a buzz.I am collecting anything from beyonets to pen knives (folders).In tend to use this site quite a lot and make more knive collecting friends.thanks.
