Also called a Builder's Y [Wye] Level with Compass. The model name and number does not appear on the object, but was determined from catalogue description and illustration on page 387 of the 33rd edition catalog of 1909 and the numerals inscribed inside lid (see text below.) The date of manufacture was determined from the serial number, 11203. That number places it as manufactured in 1906 based on "First Instruments of the Year" serial number chart in January 1991 issue of Surveyor's Historical Society magazine, "Backsights."
