Thank you! I knew it was some sort of reporduction since the switch is just decoration. But had no idea from what decade. I love this lamp. It filters light really nicely through the glass. We bought a 1890s farm house and I found a box of things in the attic. Lots of older kitchen equipment. But those have patent numbers so I found their worth. Since the house is old, I really don't want to decorate it with pottery barn stuff etc. I would like to get as much period pieces that would of fit in the house at the time it was made.
