I have happened to round up a set 4 aircraft lap belts and and shoulder harnesses (enough for 4 seats). They measure 55” fully extended from mounting hole to mounting hole. They are 3” wide and are in great shape. They are off or a military aircraft but are not WW2 vintage. These are getting harder to come by and whenever I manage to get them they only last a day or 2 at most. I am not interested in any trades. First come first served.
