Vintage Crystal Labs Metronoma Bakelite Tube Type Metronome. I cannot find a model number. I believe this is a tube type device, and I also believe this is from the 1950’s. The Tortoise Shell Bakelite Case is in good condition and free of cracks. It does have a few scratches which I’ve done my best to show in my photos and attached video. The original power cord is in good condition. It works as it should, giving both an audible beat as well as the flashing light and it adjusts speed properly by turning the dial. Pretty cool. If you wish to see it in operation please click on the link to the YouTube video below. Sold exactly as shown
