I picked this guy up on some auction site which sells lots of stuff; I'd love to find out more about it. Have you seen me? The only logo is located on the bottom of the support towers, its of a tennis racket with a crown above it. I added the 90 degree brackets on the turntable to ease up the lateral pressure on the cross bar when I'm stringing crosses. The drop weight arm doesn't have a stop so that's why its leaning on the racket support. I don't know if the stop is broken, or if the machine was made this way (I'd like to know this as well). Btw, its a clutch type, not a ratcheting type of drop weight mechanism. Any info is appreciated. Thanks!
