A solid dark wood stand, comprising 3 sections and measuring 19" in overall height, is supported by 2, 15" tall screw-in wood spindles. Section 1---the wood base---is 15 in diameter. Section 2---three, 2 tall feet/stands---are attached with dowels/screws to the base and extend underneath (photo 7).
Section 3---a wood strip---is attached to the spindles by round, screw in brass mounts, left & right, to form the top of the stand (photo 5 & 6) with an additional center screw mount which is bent and non-functional. A round brass plate measuring 4 1/2 in diameter would screw into section 3's center screw mount (were it functional) acting as a support/lid for the heavy, thick hand blown? The glass measures 14 1/4" in height and 4 1/2" in diameter. An opening in the wood base houses the bottom of the glass tube. See photos 8, 9, 10 &11 for close-ups of the wood apparatus equipped with a rubber gasket and two individual brass fittings.
I found it resting inside the glass tube, positioned as seen in photo 1. Photo 2 shows the brass fitting protruding from the base as another possibility. A round brass fitting is attached by a long threaded screw which extends the length of the wood apparatus and fixed with a washer at the apparatus's base (photo 9). Photo 11 features the other brass fitting which attaches to the above.
The apparatus does not appear? To be a hollow container making the two brass fittings key to its function.The item "ANTIQUE CIVIL WAR ERASCIENCEVACUUM DEVICEONE OF A KIND" is in sale since Tuesday, March 31, 2020.
