My Grandfather made this electrical testing equipment.  I assume it dates at least to 1930 give or take a decade.  Nob and tube wires and testing nobs, with the skeleton key drawer (no key...we opened it looking for gold!).  The gauges are in good condition for display, with lovely patina on the "Weston" meters.  The bottom drawer clips off.  The drawer is stiff but it opens. It would make a great steampunk display, given the gauges and interesting appearance.  We did not test it!
