New Old Stock 1960's 1970's.  My grandmother had an antiques store from 1950 to 2002 in Bellingham Washington--Cheryl Leaf Antiques, Gifts and Coins.  She was obsessed with antique lamps and antique vintage lamp parts.  Her entire basement was devoted to these parts.  I still have boxes and boxes full of parts that I will be listing in the next few years...Yes, it will take that long.  Please check back for more treasures.
