Hello, All. I have been clearing the workbench, (again), and it's time to find out what these things are. At top is an unknown piece, my guess rigging? 8-1/2" x 4" x 1-3/4", with EP556X in raised numerals. Next is an un-mamrked 1/2" drive ratchet, approx. 10" long, smooth round handle, recessed areas on handle, but no markings.. The 2 at bottom I am guessing are shop made. The one at bottom left is approx. 5-3/4" long and the slots are 3/8" wide. The piece at bottom right is approx. 1-5/8" x 4" x 1/4", beveled edge, but not sharp, 4 tapped holes , all are 1/2-13 thread size. Regards, Lou
