Rare, excellent condition, all brass, original patina. Disassembles easily in 2 parts. 9" tall, 6" inside diameter, 6 3/4" outside. Female connector and 4 large threads on both ends. 2 large handles to tighten connectors. Most probably used on a large fire truck but could also be maritime. Can be transformed into a cool desk lamp by adding a glass glove between the two parts.
