Vintage Simmons Omega Audible Repeating Darkroom Timer M-59 J-2970.

This timer works great except the audible part doesn't ding like it is supposed too. Click the button and the light or whatever is plugged into the outlet comes on for the desired time then cuts out and timer automatically resets until button is hit again. Also has focus outlet that can control another item that will come on when switch is flipped. Wire needs to be anchored but is still in good condition. This timer came off the USS Kitty Hawk
