Very much a guess, couldn’t find very many listings for it in this condition to base it off  of.

The issue marks were removed from the case back one reason I got it cheap years ago. When someone in the military takes something without permission, they sometimes remove the issue marks thinking they won't get caught. On one of my WW2 deck clocks someone tried to remove the US Navy mark on dial there deep engraved so he sort of ruined the dial a little. The Elgin timer does have some odd issue marks most of the time their blank no marks but this one has a serial number and USA under the serial number on the case back I can take a photo of that if you want.

Adding to the educational value of this great thread. Here is a Vietnam era Frank & Warren Inc. survival machete and Survival Kit, Type 4 with the same accessories and edge coating as the one on page one of this thread. NOS in an Army/Navy surplus store just outside Ft. Hood, TX. They also had several early-80s dated Camillus pilot survival knives. Interestingly, I used this thread to validate the “made in Japan” sticker on my 5x magnifier. The vinyl accessory cases have also stood up well; must have been decently stored. 

My guess is the scabbard is original but not original to the knife. The knife was imported for sale at places like surplus stores. Before China entered the market. 

My knife collection is very large.  Overall, it is an investment to pass on when I pass.  With that in mind, I have kept good records.  I recorded the date I acquired each piece, what I paid for it, and record auctioned sales by date for most of the high end knives.  This way, should I decide to thin out the collection, or if my family decides to sell it off, they have a good idea of what they are worth.  I would hate to see a $5000.00 knife get sold for $200.00.  

From my estimate. I’ve seen 1 sell before. Just going by that. 

Is the M8 style sheath in your pictures original to this knife?  Does it have any identification markings?

From what they wrote it sounds like a guess.

. Friends ribbing friends . . . . . . .   London Jeeping friend has been building a flat head V-8 Hot-Rod.  This is how he made his chassis-engine moveable in the garage and saving valuable working space fitting wooden discs to roll it around.  He's trying to emulate the returning servicemen and building a California Rod.  I asked him if he was going so far as to emulate the wartime lack of rubber for tires as well . . . . . . . . . .  😹   And of course there were the quips about was it a Roman chariot as well !!!!  😂       Norman D.

. Hi Johan,      Thanks we had that one sometime in the last year, I liked it because local friend Mike was a photographer before retiring,  he even ventured into various war zones, he never mentions it, his wife spilt the beans one evening about being in the Kosovo-Albanian conflict 1998 period.     Norman D.
