WWII Case Survival Machete US Army Air Forces

This is a Case XX folding survival machete which belonged to my father who became a pilot towards the end of WWII. It has never been rusted out and cleaned up, only wiped a little when taken from the garage. He may have sharpened the blade many years ago. You can see some fine scratches on the Case xx side of the blade. Note any other small imperfections. Please thoroughly examine the photos. Please enlarge the pictures to be sure of what you are getting, or ask for another view. If anyone has any info to share on this knife that I can add to the listing, please share. I will soon be listing a B10 and B15D flight jacket. A return will be accepted only if I have misrepresented the item. Insurance will be included in shipping. I will ship to foreign countries describing value and contents honestly on customs forms with the buyer accepting all responsibility for import issues, regulations and costs. I believe some countries may confiscate weapons. Foreign shipping costs to be calculated.
