Beautiful Handmade Medieval Black Leather Frog with Casting.  See 2nd pic for actual color - thr front pic is rather warm-colored, but it is truly black and unworn. 
This is great quality frog/scabbard holder with casting and handmade brass fixing elements for width adjustment. 
Great looking piece which works good and looks very authentic made from natural leather with high-quality hand-casting rivets. Materials: Great quality leather, handmade brass clasps.
Measures approximately 8" and 10" long by 5" wide at the belt loops.  Adjustable sword/sabre/dagger/scabbard clasps.
100% unique handmade Armstreet design (original new item cost is 64.00USD)
This item was never used but does have some shallow storage folds (see pics) which should not affect use.

Thanks for looking and happy bidding!
