Embossed R-5088 bushing or wall tube. height 5 inches. Heavy. I don't think we have a numbering system for glass bushings like this yet--- that is on my bucket list. This one's the tealer side of Aqua. the right hand one in the photo. The top edge has a slice 1 5/8 inch long and up 1/8" deep-- barely visible from the outside edge side view, … slice leans inward. Not selling the left one. The rest is very clean glass, very smooth, no chips, flakes or roughness. $120 plus postage.
