Wonderful barn find!  1/2" gauge wrought iron hook with split shank, measuring 7 5/8" long on the outside, with 1 1/4" wide shanks and a 1 3/4" wide hook.  Only a bit of the original wood remains.  The inside dimensions of the hook itself are 1/2" at the opening x 1 1/4" long x 7/8" wide.  It is blacksmith wrought, with the sturdy joint slightly visible.  Saved for years in the family barn, Marlborough, NH.
