Looks to be in near perfect condition. It preforms calculations as expected.

This calculator came from a locally-owned electronic repair and sales business that has closed.  They built and repaired tube amplifiers, ham radios, stereo equipment, and other electronic gadgets throughout his lifetime.   The owner passed away in 2018.  I bought the remaining contents and inventory from a relative who needed the stores warehouse cleaned out. I have been trying to sort tens of thousands of tubes, gadgets, dusty boxes of parts, junk, vintage electric surplus, and new-old stock parts. I list these items as I get time.
