Is it a Stiffel or a cheap knockoff?

I bought a floor lamp off eBay; the seller said it was a Stiffel. Got the lamp yesterday and proceeded to put it together. Well, the base of the lamp has a few scrape marks on it, which I was going to overlook because I like the lamp so much, but then I noticed two bad dents in the base. I then noticed the “made in China” label on the bottom of the base. I don’t want to assume that anything made in China is cheesy, but it’s possible the lamp is a knockoff. I’ve already sent a message to the seller about the dents and scrapes. Any idea where Stiffel lamps are made? If not, how could I find out? (I’ve browsed the web, with no luck.) Thanks.

This Stiffel lamp is “imported from China,” according to the description.
