UNKNOWN MAKER OF BEAUTIFUL "LADY WITH HANGING GRAPES" LAMP !!

I purchased this lamp at a yard sale, approx. 2010..  The woman who sold it to me asked me to make an offer, after she stated it was in her home for over 20 years (she had bought it from a sale).  She also stated the part where the lady and grapes were, it was broken, and it wouldn't stop from shifting side to side !!  I offered her $40 because I loved it, and took a chance it wouldn't cost me much to have what ever was broken, fixed !!  I took the lamp to a local lamp store, the repairman took off the felt that was on the very bottom, tightened a screw, and charged me $24 .........  He had asked me what I paid for  the lamp, and after I told him, he replied."GREAT BUY, IT'S BEAUTIFUL" !!!   Any Information I can receive would be helpful !!  Thank you !!
