Hello, Piece at top left has in raised figures F & H 56 on the head of the bolt, and a bunch of other stamped numbers at the top of body, approx. 2" diameter, and as it sets approx. 3-1/2" tall, fine female threads.The wrench at top right is stamped 207 Forged in USA, plus the opening sizes 7/16 and 1/2. The piece at bottom is unmarked, and is non-magnetic, overall length is 5-1/2". At first I thought saw handle, but the bottom of the slot is solid, no place for a blade or file tang to pass through. Thanks, Lou
