Hello all, There is an NOS Oil Pressure Gauge on E-bay. Item#320184764342. Cat#7F0084. This is an SW Wings gauge which I believe was original equipment during some production run of the U series model tractors. I bought one from the same seller on aution last year. It has a few scratches on the metal but is new otherwise. These old type gauges are light years ahead of the crap cat puts out now.

One more thing, from my serial number list, the gauge I have and this one were manufactured in Jan 1952.

You might want to be careful when handling these guages. I bought one several years ago that was obviously never used but broke off right where the threads started on the rear fitting. I didn't horse around with it, it was just very weak and brittle at that point. I didn't bother with a repair attempt because it is a weak point and I felt line vibration in time would cause it to happen again. It might have prevented the problem if I had reinforced it with JB Weld or something before attempting to mount the gauge.
