Looks like some kind of level, that is put on the outer edges of box to level it. Looks pretty heavy duty. Looks like aluminum
Surprised no one else has asked, why did your neighbor buy something he didn't know what it was?
Because he makes a lot of money and likes unusual items. So he buys them.
What is mounted on the top edge? How about a picture from that view.
My neighbor bought this yesterday. I think it has something to do with sighting weapons.
Come on guys you dont know what that is?
Its so easy, it is the ThingAMaBob that we all need to connect the Whatcamacallit to the DooHicky. Without that the Doohicky is just a wortheless Thingamabob and the whole project is Fubar'd
Dunno, can't help.
But, is that an NMLRA decal on the window of your truck?
Looks like a Jig for depot level work on either aircraft or ground support equiptment. The level would ensure level and the holes may be for locating holes and/or having to be bolted on supports already on the equiptment. If you can find any numbers on it or the box PM me and Ill see if I can get a read on them for you.
I'm not totally sure but believe it to be a flanginator triscopic self aldjunating front section from a late 1950's era tabletrunnion based gyro embedded wiscoping boomswigger (the trusted #35 series). Of course if you looked just inside the third outboard skyopter mounting flange, you might see a serial number just above the rotator sliding emblanking die shearing post. If so, and the number starts with 005-4XX it was an early model not in use anymore being replaced in the mid 60's by the self flappinating resurgent model which was a little lighter to carry around and didn't need constant leveling.
Hope this helps and like I said...... I'm not totally sure!
well, let's just say you'll never need a wiscoping boomswigger again!
