History I.D. This Clock?

A buddy acquired this clock. Anyone know what it's from?

 

Looks like a 1951-52 Chevrolet Special Deluxe Stem-wind dash-top clock

 

Is the "S" to "F" under the 12 for Saturday through Friday?

Cool if it is.

 

HAHAHAHAHAHA...YOU YOUNG GUYS SLAY ME....that's fast and slow for adjusting to keep correct time

 

Nice to be called young

Hey, 7 notches, I just made an educated guess

 

Back in the 50s Mom told me the car clocks never worked well and they didnt work long

 

^ True but even a broken one is right twice a day.

 

I've never had a chevy wind up clock that didn't work!

 

my '53 chevy was my daily in '66 and the clock was the most reliable thing on it! thanks for the i.d.!
