Never seen that before. Looks like just an overlay stuck on a regular gauge. Wonder what the small print says.
I'm going to look at the car maybe this weekend, it's a 4door with some weird stuff on it, stuff I've never seen before. It does look like an overlay...
A friend of mines Mustang II used to have a speedo similar to that. He said that the car came out of Canada.
Seems like I remember someone posting a photo of one a while back. I do remember it being from Canada.
My mom had a couple of cars when I was growing up that had both. Her old Cougar did, and so did her Granada. But living here in the Inland Northwest, I am sure that a lot of the Fords where imported from Canada.
