Cigarette Lighter ID?? Unique

I found this lighter at a sale. Is it a stock piece off an old jalopy or is it some kind of aftermarket fancy thing-a-mah-jig?

Here's some pics:







Any info is greatly appreciated...

 

No idea, but cool as hell.

 

What about the notch...is that just a notch, or does it hold a bulb to act as a map light? JCW offered several like that, and probably Detroit did too. Any patent number on it anywhere?

 

Maybe to hold an extra cigarette?

 

It says:

PAT & PATS PENDING CUNO MERIDEN CONN 12v

No Patent Number

 

a quick Google search shows that they are still in business an they make water filtration equipment. founded in 1912 and are now part of 3M

 

You're right about CUNO. I did an eBay search and I found a bunch of car lighter listings. Hopefully that'll help. It is unique (uni-Q as I like to say). No idea what make or model this came in, but I bet they're all pretty universal.

 

It's to hold a lit cigarette and snuff it out on the end for those who didn't care about the interior of the vehicle, much.
