Description

thanks for checking out one of my items, if you like this you will probably like other items i have, i get tons of stuff in diverse fields of collecting and use. NOTE: i will always combine items to save you shipping cost.
I HAVE NOTICED THAT SOMETIMES NOT ALL PHOTOS SHOW UP ON TABLETS AND PHONES, IT IS BEST TO VIEW ITEMS NOT ON A MOBILE DEVICE...
THIS ITEM IS----one of the many items i was lucky enough to get from the Awesome collector/dealer/curator ELLI BUK (google him), lots of science stuff, paper and Tools, a bunch of it i just dont know what it is for or from, so you can really find some neat stuff by checking my other auctions (syottoys) and searching for Elli Buk, or just search for Elli buk and others might have some of his cool stuff up. anyway
THIS ITEM IS: i cant figure out what this item is for, bracket that swivals 180 degrees, with spinning part at other end, 3 screw holes in the end. is this for some sort of lamp. love it, great form, very old and cool.
