I have an Old Folding knife that was used in WWII by a friend of the family. It is heavy and when opened , About the size of a Mark 1 Navy Deck knife. No numbers, Just says Colonial Prov R.I. on the blade. It probably should be in a museum. I cannot find a picture of it anywhere on your site. Thanks
You probably have the Pilot survival knife, are yo able to send an image?
