289 Speedometer on eBay
 

This isn't mine, I just ran across it while parts searching. It's rare for sure, though I'm not convinced it's an original. The screws holding the face on should be on the outer edge I think. Possibly a change during production?
Anyway, nice SW gauge for a US spec leaf spring.

Vintage Stewart Warner 160mph Speedometer Cable driven 1960s fits AC Cobra | eBay

Nice find Larry

This one pictured is for sure correct.

You are correct, it is not an original CSX2201 and later production part. Stewart Warner engineering documentation of the Cobra assembly still exists and based on that information the Cobra assembly is different in several ways than what speed shops sold. They were rare as service parts even by 1965. They had been superseded by Shelby American by May 1965 as by that time a common Stewart Warner retail unit was listed as the available service part.

The only assembly number I have for the Cobra unique assembly is a Ford engineering one, XF-152470. (The Ford specified Stewart Warner components for CSX2201 and later Cobras are linked to Ford engineering 'experimental' numbers. Some were itemized in the April 16, 1965 parts list.)

The description is not misleading to me as it says "fits-AC-Cobra" not that is a genuine original production part. (Since at least the mid 1970s it has been very common for suppliers of replacement parts to Cobra owners have used descriptions like "as original" or "fits" to describe parts they offer. If the buyer realized, and many did not, that the new part delivered was not exactly like the original they were replacing the common counter response was something like 'didn't say it was original just that is works'; I was certainly told things like that often enough from suppliers from the west coast to AC Cars themselves.)

Just to illustrate what an original gauge looks like, here's one from CSX2337:

It does state refurbished.
Think it's one of the units made to look original
This can be done with new gauges for workability.

I know the backstory on this gauge. I purchased a tach from Chris (the ebay seller) and I commissioned him to build the corresponding speedometer. What is up for auction was his first crack at the speedo. I had him correct the screw placement and hashing for the gauge I ended up purchasing. If you need something SW related, Chris Schlaff is your man. He was fantastic to work with -- highly recommended.

Here's how mine ended up (sorry for the glare). I think the sweep is a bit more than the original but overall I'm quite happy with the results.
