*SOLD* Very cool and unique Stewart Warner 5k tach. I believe this may be a very early conversion of a speedo into a tach. It was clearly professionally done including the addition of the plate around the housing so that it can be rear mounted. It has a crescent needle that is the same as can be found on SW survey speedometers and 35-36 fords. It measures 4 3/4 and can be rear mounted into a 4 3/8 hole. It is in really good condition and should function without issue. I have only seen one other example like this and it is pictured below. This would look great in old purpose built pre-war racer surrounded by other crescent needle SW gauges. $350 + shipping
