Metal Lion Lamp: Origin and Age?

Hello!

This was a recent auction purchase. Was only a few dollars, so not much of an investment. Obviously, it is a lamp base; however, I have not been able to find anything like it. I am most curious about its origin and age, if anyone has any ideas.

The lamp itself is metal, with screws behind (but not connected to) the lions, which was likely for whichever shade it came with. No marks on the lamp base anywhere, unfortunately. The socket is branded S&S and the cord is cloth, although the plug has been previously cut off.

Any help is appreciated!
