This very old knife sheath is 9 3/8 inches long overall. Its opening is 1 1/2 X 3/4 inches oval. It is unmarked but does look similar to some of the sheaths that I\'ve seen with vintage Marbles or MSA knives. This particular has had some aftermarket / folk art decoration added. There is a very nice scene of water, grass, and cattails carved onto the front of the sheath. It is used and has lots of wear. The belt loop is very thin and soft. The lower rivet appears to be a replacement. The tip of the sheath is worn and split (see photo). It has a faint tobacco smell. Despite the damages I still feel that it is an overall nice antique sheath with honest wear. The leather is soft and flexible. This item is sold AS-IS. Shipping is $3.65
