Glass lamp

I purchased this lamp a while ago at a second hand vintage shop. Recently, I decided I would breathe new life into it. I added a new shade and replaced the missing crystals. The wiring was in excellent shape so I left it. Along with the regular bulb at the top, it also has a smaller bulb in the base. There is a Paul Hanson sticker on the bulb base. I'm not sure if there are any markings on the inside do the bottom casting. I would need to take the lamp apart to see it. It looks to me to be 1970's?? Can someone give me some info?
