Thank you for the photo tips! I agree Ross, the light is too blue. The photo makes it look like it has a blueish or greyish cast, but it is clear glass. It was just so hard to find a good spot that was free of clutter, haha. Thank you also for the link to Harder's site!
Thank you Chris for the link to the older post! I have seen some of those as well, with the silver collars all dating between 1880's-1950's, which made me think mine dates somewhere between 1880-1900. I don't think mine ever had a silver collar though.
