On the speedo unit there should be a paper label.
On the label is some info like manufacture date.
If the label still exists, does the date tie in with the car's manufacture date?
Also on the label is the part number. You can look your car up on ePer ( eper.fiatforum.com ) and see if the part number matches your car.
Thirdly, the other numbers refer to the number of pulses the speedo is expecting for a distance travelled. If you can persuade someone else to remove their speedo unit, you should be able to compare data.
for example, my speedo from a 97 TS reads :
(Date of Manufacture)
