Vintage tension pole lamp beautifully detailed!

This was in an elderly woman's house who passed, and they had an estate sale. House approx built in 1930's or earlier. Was filthy beyond belief, got it for 10$. Cleaned it to a beautiful bright silver with markings on the inside of each lamp sconce of 3593 or 3953 I forget now, was hard to make out. The pole was a cream color. I restored it before questioning the value to a black pole, and aged the sconces with black aswell. Talking to friends we were debating if the sconces are nickle, pewter? Unsure, but definitely a metal, I filed a little piece that was hanging on the inside from the mold over cast. The detail is beautiful I can't find anything comparable online. Lamps are very very fragile, unsure if they're glass or a glass type compound, or possibly just very thin.

Good
