Monday Mystery, Bernard pliers

We've covered Bernard pliers in another post but this is something different. By the shape of the jaws, the pliers are designed to hook onto two items with lips or flanges and then squeeze them together. I can't imagine a use, but the tools owner was a mechanic with Pratt and Whitney during the fifties and sixties, that might be a clue. Ideas?




thanks, Daniel!

    Prettymuch positive that the pliers' purpose* is to push a (colleted, or ferruled? Possibly flexible, or soft anyway) tube over a solid (perhaps fixed, very likely fixable) fitting (a T-shaped takeoff, maybe, or a reducer†). Is that sentence remotely fathomable?

    * For a cheap thrill, say the preceding six words like Porky Pig.

    † The engine oil return line on an old Triumph twin (motorcycle), for example, has a solid fitting where it enters the oil tank (dry-sump engine). This combination fitting has a "T" to direct some oil to the top end (rockers, etc.); and to impel oil to the bits up there, its ID is reduced (= more pressure). Meanwhile, the rest of the oil goes straight to the oil tank.
