Antique c1910 WW1 Naval Military Nautical Rule DARGUE BROS HALIFAX Crows Foot

Antique c1910 WW1 Naval Military Nautical Rule DARGUE BROS HALIFAX Crows Foot I am currently offering this wonderful  WORLD WAR I , nautical rule or ruler. The quality is fabulous , and this was made by the top scientific instrument maker DARGUE BROTHERS LIMITED , HALIFAX. This is made from what I believe is either Ebony or Lignum Vitae wood and the rotating piece and bar are all made from brass. This is stamped DARGUE BROTHERS LTD HALIFAX and 2214. This is also stamped with the CROWS FOOT indicating these were from the War Department. I believe this was used by the British Navy , but they may have been used by one of the other military forces. This simply oozes quality . Please see my other items stamped with the Crows foot. They are all nice items. This has a wonderful patina and is in excellent condition and measures 15 inches x 2.    
Good Luck.   I will combine postage if you buy more than one item. DONT MISS THE OPPORTUNITY. GRAB A BARGAIN. GOOD LUCK. If you are interested in any more pieces , I will combine the postage costs for you.   I am also offering other Vintage Collectables and Antiques I have collected over the last 50 years or so
