Casco lighter

[Warren]

Before I stick this thing up for sale I thought I would tell you that I thought it came out of a early Alpine here's the picture of it I'd appreciate your all knowing comments.

Not a sunbeam part.. Looks like a usa spec car. Early alpines had the smiths lighter with a black knob with a round recess on top

 

[junkman]

Most likely an after market, or other brand ( kinda looks like a mid 60s Impala). Original cigar lighters matched the windshield washer button, black knob as Micheal said.

This shows the lighter knobs I have in our Alpines and one of the Harringtons. The photo of the Harrington was taken before the car was finished.You may have to zoom in. The other two Harringtons both had lighters with a small chrome knob.

I know what the right one also found on E type Jaguars look like . I'm fully capable of cobbling together a shortened washer pump knob. This picture is a copy from a fellow members Blackdog . I have you seem different iterations of the lighter but they all seem to have the same similar style reverse chromed or stainless steel escutcheon between the knob and the base of the lighter element. If you compare the washer knob to the to the original cigar lighter it's close but no cigar...

Thanks junk man I've looked at the Impalas and a lot of 50s cars trying to figure out what it came from, I've also got this really cool gas cap that came off of something, from the vented cap era of cars, It's like when I was digging through the trash can at a tiger restores place and I found a clock. I went home and searched for about 30 minutes till I found out it was the same clock used in a Pantera wahoo...
I admit only that I no speak early Alpine's

My S3 came with that same lighter. I assumed aftermarket as well.

Well, you can always make your own.

On the knob drawing, I must admit I could not determine the thread of the knob and stud, so I left the stud out and made the thread 6mm x 1.0 as a first cut. Can anyone tell me what the correct thread is for the lighter cartridge?

 

[Warren]

Awesome replies guys ... We had to reverse engineer the AC air filter housing as RACT and those who placed themselves as a go between were reluctant about sharing the drawing.
It may be hard to get that speckled Bakelite look through

Note - I have updated the drawings to increase the precision. I had my dimensional settings to only two decimal places (.00") not three (.001") which is required under the circumstances. Fixed now. Links above go to the new drawings.

How does the unit disassemble to check the thread?

Grab the cartridge inner core, and unscrew the knob, counterclockwise.

28 tpi
Thread major diameter: 0.212" (probably #12)
Protrusion length: 0.40"

Thank you. Yeah, I got that measurement, but it didn’t translate into a BSF/BA/NC/NF/Metric tap size as far as I could determine. I tried a 12-28 tap and a die and neither one fit. It’s also close to a 6.0x1.0M but not close enough. If you look closely at your thread gauge it’s not *quite* 28 tpi... the threads bind on the gauge a bit.

 

[puff4]

Also, mine has a stepped section on the shank between where the threads end and where it goes into the knob. Yours does not appear to have the same setup.

 

[hartmandm]

The gauge seems aligned to me. Hard to get everything aligned to take a photo.

The knob has some wiggle in it when threading it into place. The threads don't seem like a tight fit.

Maybe I don't have an original piece.

[husky drvr]

Could it be a difference in the thread form angle ( 55* instead of 60*)?

 

[Warren]

Just a comparative shot between the washer button and the original lighter.

 

[alpine_64]

Thanks for posting the comparison shot Warren,

Yes, this is how you can tell when unscrupulous people put a washer knob on a genric casco chrome colar base and then pass them off on ebay etc.

Some exceptionally dishonest people have done this then listed them as original based deliberately misleading people with the implication its an original sunbeam lighter

Funny, which reminds me of an old geezer story. " Why I remember when we were so poor we had to take a huffy bicycle and put Schwinn Stin-ray handlebars and a banana seat on it." The Pearson's solo Polo or the wide butterfly bars was our reasonable facsimile.
