Schwinn speedo question?

[HEMI426]

My question, is there a way to tell the year (date) of a Schwinn Speedometer. Handlebar mount, says made in France on the back. Thought some of you Schwinn guys would know, thanks if you can help.

Ask Andy Green [email protected] he know more about speedometers of all kinds than anyone I know. He refurbishes, rebuilds etc:

Something is still stuck to my brain telling me there were 4 digit numbers on the back of some later models in the 70s. But I also remember people not caring as long as I put their stingray face and parts in said nice chrome case...
Internal gear parts changed colors at some points too, but I had no official date stamps to go off of for reference. And have pushed most of that out of memory by now.
Keep in mind, they were add on accessories that could be bolted on at almost any time.

Made in France by Huret.
Look for that brand for compatible replacement parts.

The Schwinn Approved Speedometer you have in photo was available in Schwinn Catalogs from 1968 thru 1976. Sting-ray on face from 1968 thru 1977. After 1977 the Speedometer has MPH & KMH on face.
