This is the  Minolta FT-1 luminance meter shown in photographs (exact one).  Purchased from a local printing company auction that was upgrading all their equipment.  Stated "working when decommissioned".  Turned on and put in battery and the number moved around when I pointed it at different things.  Looks like it works as intended but am not an expert, just a liquidator.  Right of return for 14 days. Found on internet: Specifications: Type Reflex-viewing spot-reading automatic/manual luminance meter Measuring method Reflected light by silicon photo cell with 1° angle of acceptance Viewing System Focusing through-the-lens reflex type Objective lens 85 mmf / 2.9 Angle of view Circular 9° with central 1° marked circle Magnification 2.96X focused at infinity Focusing 1m (3.3 ft.) to infinity by objective single helicoid; eyepiece adjustable from 4.6 to ±2.7 diopters Minimum measuring area ?15 mm at 1m (?2.4 mm with close-up lenses) Response time Automatic: Approx. 3 sec. from 0.01 to 99900 Manual: Approx. 2 sec. from 001 to 999 Analog: 90% within 0.4 sec.
