Genuine Name Plate for an Elgin National Watch Company naval marine chronometer . This US Navy brass plate is an original new old stock plate that dates from during WWII.
It is made of brass and was never used since Elgin only completed a few chronometers before the war ended.
It measures 3 3/8 x 5/8 inch and was designed to be attached to an Elgin chronometer box made for the US Navy. The pictures show it next to a US quarter to give size perspective. Sorry, box and quarter not included.
