For your consideration are two vintage chrome plated brass spring-loaded push-back glass fillers, as shown in the photos. The one is marked Tyson Metal Products Pittsburgh PA. PLEASE NOTE that this one, it’s upright is bent. I suspect it can be bent back into proper straightness, or perhaps used as-is. The other filler is marked Central. Both of these items appear to be pretty old. I found them in a box of miscellaneous hardware and have not tested them and cannot guarantee anything about them. They make work as-is or may need rebuilt / new seals, or ???. You are purchasing these items as-is and as-pictured. Thank you for your interest.
