This is an unusual cast iron surveyor surveying level that is marked on the brass top of the level Gray Instrument Co. 
"Queen Instruments" Phila, PA USA and then the serial number of 5453.  The vial bubble is good.  The overall length of the level is 18 inches.  The level unpacked without original box weight is very heavy being 7 pounds 14 ounces.  It has the original wooden box with it which has the brass tag on the top with Gray Instrument Co.
