I've been collecting these for several years with no specific project in mind, so it's time to let them go. This post covers the Deluxe gauges. To see Twin Blues or Greenline gauges, check out the other 2 posts. 80psi Oil Pressure with no bracket dated I believe February 1968. I carefully pulled this one apart to clean the face and glass and to lubricate the mechanism. $20 shipped. Battery Volt gauge dated K5- not sure if that's May 1966 or later. I pulled it apart to clean the face and glass. $40 shipped. 100psi Oil Pressure dated September 1972. I carefully pulled this one apart to clean the face and glass and to lubricate the mechanism. SOLD Water temperature dated G6- not sure if that's June 1963 or later. I carefully pulled this apart because the needle would not move. After carefully cleaning and lubricating the mechanism, it works beautifully and rises to 210* when bulb is submerged in boiling water. SOLD Service manual from 1968. Tons and tons of info in there.
