Measures: Box – 5” long, 1.75” wide, 1.5” tall
The old saying “Necessity is the Mother of Invention” certainly fits here! So, you put the bottom of the magnifying glass wire into the top of your spool of thread, flip up the hinged magnifying glass, hold your needle and thread beneath it and voila! You can see to thread the needle! This piece is in very good condition and it works, I tried it! The box is original, it has some paper loss and one corner has a tear. This was patented and manufactured by William Adams, Optician of 332 Boylston Street in Boston, MA. According to my research it was patented Feb. 15, 1916. Great for display in a collection or to be used for it’s intended purpose!
