Very nice looking military altimeter. Marked US on the reverse. Taylor of Rochester has apparently been making altimeters since WWI. I searched hard and have not been able to find another example of this model for comparison so even though this sure looks old I can not accurately date it. The dial compensates up to 16000 feet. I would assume this is rather old as more modern aircraft would, I assume, have an altimeter mounted on the dashboard. Nice and clean and in great shape. F\Leather case is also in top shape with only small, partial tears on the smaller side flaps (See photos). Otherwise no damage found. Neat item for sure but more information would be greatly appreciated.
