Acorn Dappled Glass Brass PendantReclaimed Brass Passage Pendant Dappled Glass Found in German ship at the ship breakers last year that had over 100 of these very impressive passage lights. Cast serial numbers in the stem, thumb sized wings to twist the threaded cage off the light, making access to the original porcelain fitting inside. A real asset to these lights is the attractive dappled glass which, being from the marine industry, is as thick as you would expect it to be. IP56
