One Hickok Model 540 Dynamic Mutual Conductance Tube Tester.  This tube tester has identical circuitry to the Military I-177B and this version was given to the Army for military use.  Tested and works. Very close to my calibrated I-177B. May need some calibration tweaks.  Power cord and blue sheath on cap cable were changed. Everything else is original since its last calibration.  In good cosmetic condition. Shows normal wear from age inside and out.  Glass is cracked on the AC volt meter, but is functional and working and can be changed. Thanks for stopping by!
