Vintage Darkroom Photography Equipment

The Lektra Laboratories TM-560R is a specialized electronic interval timer designed for professional darkroom use. Manufactured in New York, these units were essential for precision timing during photographic printing, particularly for controlling enlarger exposure durations. The heavy-duty metal housing and industrial-grade toggle switches reflect the robust build quality of vintage electronic laboratory equipment from the mid-20th century.

• Dual control dials for precise interval timing settings across multiple ranges
• Industrial toggle switches for Power, Start/Reset, and Time/Focus modes
• Side-mounted outlets for integrated enlarger and start trigger connection
• Grounded power cord and integrated wall-mounting keyhole slots on the rear panel

Condition: Hammer-tone gray metal housing shows significant surface rust on the side containing the power outlets. The black faceplate has light surface scratches and general age wear. All original knobs and toggle switches are present and appear functional. Power cord is attached. This unit is untested and sold as-is for parts or restoration.
