Yes - The other side of the sheath is marked the same as in the photo you posted.

I bought this at a large auction of Militaria items that a deceased collector had accumulated over 60 years. All items were original so I trust that everything is correct on this piece. Also in the same lot with the Ka-Bar was an Air Force survival knife from the 1970's and a very poor condition M1 Carbine bayonet.

I sold those two to another collector several days later and kept the Ka-Bar and covered the cost of the purchase.
