1963 Westclox Pat2542430 What's it for?

I came across this clock in my basement treasure chest, but I cant remember what it came out of? It has Nov 1963 stamped on teh back along with the Pat 2542430 ,2858029.
anyone have a clue?

 

This has to be the most obscure question I've ever heard. Keep me posted. Gary

 

It kinda looks like the clock my Grandma had in her mid 60's Pontiac Catalina, but I was way to young to be detail oriented back then. This might give you another spot to look though.

 

Im now thinking 63 Rambler?

 

looks like MOPAR numbers

 

Looks like a Rambler. Go to this website and scroll down almost to the bottom: http://sites.google.com/site/identifyinginstrumentpanels/home/clocks-page-4

 

With a Nov 63 date code it must be a 64 model car. Remember the new models come out in Sept of the previous year.
