The image shown seems to be a brass disc with a removable brass disc insert that can be removed in order to choose two height levels. The indentations in the middle of the base and the insert are obviously intended for the tip of a spike, tiptoe, or cone, so the function of the device would be that of a coupling disc, sometimes called a "floor protector" from a non-audiophile POV. What is the opaque looking element shown at the bottom of the brass disc base? It appears to be a plastic insert of some kind.

The middle filler piece sits inside the larger piece. It is balanced by a small brass protrusion inside and in the center of the larger piece. The smaller piece has a small indentation on its bottom to center this protrusion, allowing the smaller piece to move slightly. The hole in the small piece is threaded, but has room for a small spike without hurting the threads.
That's the best i can do. I don't recall the price. I bought 8 of these many years ago. It was well under $500.
I can have them made in a machine shop, but it won't be cheap.
This is the only device I've noticed for sale that is similar to what you describe. However, it does not have an indentation on the top in order to accommodate a spike, if that is an issue.
