I know the oliver 80 models had a white faced amp gauge while the water temp and oil pressure were black, My 80&#039;s with original guages are 1946 and 1947. But my 60 is a 47 and has yellow gauges. My one 80 has never been outside overnight and has original colorful decals, paint and tires so I know fading has not gone on. I know I&#039;d be interested if one of these reproduction gauge companies would reproduce the correct ones for the earlier Olivers/ oliver hart-parrs.
