Dealer Notes

Serial number 9686 represents a classic era of American tool manufacturing. While one backstand is missing, the core mechanicals—including the independent drive system and spindles—are in good operational order. This machine is an excellent choice for a shop that requires a "cut and color" station in a single, space-saving footprint.
