I just bought it its the first one I have owned and I don't know to much about it other than I like it. From what I have seen it seems to have been a clock but all the pictures I've seen look different from the actual thing. Any information will help. The pickup I'm asking about is on the left of the photo the one on the right is my dads and is a 1967 C20 I don't believe it has that gauge. But the gauge in my pickup has no needles or anything clocklike it is purely just a lense. Thanks. 😃 🇺🇸 If you need to see photos of the gauge I can email you a photo of the gauge so you know exactly what mine looks like.
