This is an old Adam play cue. It has a bolt, but it was stuck and wouldn't come off. There's no Helmstedter marking, but I believe it's a similar old model. It has brass pins and rings, and both the shaft and butt material are good, providing a great feel and sound when hitting. It's an 18-tooth piloted joint, and the tip is old and hard. Please refer to the images for the weight. There's a slight warp when connected, but it could be used normally if you pay attention to the direction. There are no major dents or cracks, but there are minor dents and discoloration of the metal parts, which are signs of aging. I liked it, but I'd like to pass it on to someone who will use it to organize my equipment. Shipping included, and a portion will be donated. Only the joint cap for the butt is included.
