This is a early 1970's AIRGUIDE Marine Speedo like were placed on Correct Craft Boats. I was looking for an early 70 Ski NAUTIQUE for a project so I picked up this period correct never been installed speedo with white face gauge.  I ended up picking up a 68 Ski NAUTIQUE which requires an older version of Air Guide Speedometer. This unit has never been installed comes complete with the screws to install the speedo. Also, this version can be illuminated if you desire it too be.  The Chrome is original and in excellent shape. The box is a slightly worn for being fifty years old. The gauge itself is in MINIT condition.
