What speedometer is this?

I decided to check the date on my speedo to see if the mileage may be correct (). 1978 Targa, speedo dated 12.75, there goes that pipe dream...

But, while I'm at it, what did this speedo come from?

Electric, not mechanical
12.75 date
180 MPH
911.641.534.00 P/N

I think your right, I found the PN in a PET as -76 Carrera 3.0. But those never made it to the US and they wouldn't be MPH, right?

Cool, my beater Targa is part 930 Turbo

Edit - Just realized the UK still uses MPH, who would have thunk

Dunno the answer because I don’t know if Carrera 3.0s were sold in the UK. If so, didn’t they have MPH speedos?

I assumed all the turbos got either 180MPH or 300 KM/H speedos depending on market, and the combo MPH/KMH gauge later on - but PET says I'm wrong, ho hum... Guess I should check the part # on my 180 MPH speedo...

As Ivan said, 911.641.534.00 is in PET for both US and RoW 1975-1976 Turbos, and also correct for -76 3.0 Carreras (RoW).

There's a different part # (930.641.506.00) for a 180MPH speedo w/ 50-section tires.

The 1974-77 US 2.7 Carrera also got a 180 MPH speedo - 911.641.506.00

It looks like RoW PET for later cars shows 250 KM/H for SCs, 300 KM/H for 930, a 150 MPH (930.641.508.00) for 930 -79, and a combo 170MPH/270 KM/H (930.641.508.00) for 1980-on.

Yup, same part # for two different instruments - neither of which is 180MPH...

1989 RoW PET still gives the same # 930.641.508.00 for the combo, with an annotation "(GB)(HK)", but US PET gives 911.641.517.00 for the combo 1980-1989, with no differentiation for 930/911.

Weird...
