The blade from the guard measures just over 6 1/2" long. Overall length tip to tip is about 8 3/4". It has two grooves on one side of the blade and one on the other. Looking from the top, the blade is quite thick near the guard then it tapers in and flares back out again toward the tip." It is the original length to the sheath and the bag that it is in would have covered the whole sheath if it could slide over it. The whole sheath was covered in old black electrical tape....I removed some off the handle to get the pin out. I did not pull the rest out of the bag as it is pretty tight in there. As you can see, the blade has been sharpened a bit and will need a good polish to bring it back. I really think this blade is worth it given its fine features. I did not touch anything else on this blade." The tang may be signed but I did not disrupt any of the rust as you can see. The blade was purchased from an Estate Sale Picker who said,"The son of the veteran talked about his dad and he said that his dad fought at Tarawa and Okinawa". So I'm guessing it was picked up in Tarawa.
How old do you guys think this is? Anyway to tell?
