For you consideration, I offer a grouping of hanging oil lamp parts. This group consists of two small brass chain stops; two larger brass chain stops with old iron chains still attached; nine feet of unused old brass jack chain; twelve each of two sizes of "S" hooks; seventeen brass or copper waning moon pieces. I have shown ruler measurements of all. I do not really know what the moon pieces were used for but they came to us in a collection of hanging lamp parts many years ago. I also believe that the larger chain stops with the attached chain were from a cast iron fixture. I have not attempted to clean any of the tarnished pieces. They are all in good shape. Check my shop for other items of interest.
