Code BA15062001: Early 1900s French Surveying Compass in Leather Case

This is a rare and nice French surveying compass that comes in a leather case. I would date this compass from early 1900s. It is in full working order. The compass is housed in a nice nickelled brass case still in excellent condition without dings or dents. It is engraved with retailer's name and address: "Maison de l'Ingénieur Chevalier Opticien, Place du Pont-Neuf, Paris". The dial is made of metal and has silver color. The dial is covered with a flat beveled glass crystal free of chips or scratches. The quality bar needle is silver and blue in color. It has a jewelled brass cap. The compass has also a clinometer function with a nice hand to this end. There is also a tractable lever on the side that can be used to display the compass vertically and use the clinometer function accurately. The transit lock can be activated by pushing the button under the loop. It needs to be pulled out in order to release the needle and use the compass. The leather wooden case in in excellent condition for its age and opens and closes as it should with a sprung push button on the side. The compass is accurate and finds North without any problem. This is a large compass since it measures 61mm in diameter excluding the pendant and ring. The external leather case has a pear shape. Nice and quality compass.
