We have these four (4) aircraft tiedown turnbuckles. These came off from a decommissioned aircraft carrier after the 2nd WW. These have been stored on a shelf in a garage since at least 1960 or longer. Somewhat dirty due to storage and will require a darn good cleaning, but they work properly/correctly using 5/16-3/8" link chain for the tie down. We may have more than four, not done cleaning out the garage.
