Liberty "Dome Top" Spark Plugs

Post by CudaMan » Tue Oct 12, 2021 9:25 am

I picked up a tub of five Liberty "Dome Top" spark plugs for a Model T at Hershey this year. Now I'm hoping to make some boxes for them. I only found one picture online of what the box looks like, does anyone here have an original box they would be willing to part with, or flatten out and scan, or at least take good, straight-on pictures of all sides and the ends so that I can make new boxes for these plugs? Thanks!

p.s. The plugs I bought have 1/2 inch pipe threads to fit a Model T. The plug in the picture is just there to give an idea of what the box looks like, it isn't one of the plugs I bought.

For the plugs to survive for many years is one thing but the neat box that they came in would be another! You can usually see Champions, Blue Crown, AC and maybe a few others but not this one. They would be a real collectors item themselves. Good luck!

What Fun!
That's the first of those I've seen.
Thanks
Rich
When did I do that?

Here are some pictures of the plugs I got at Hershey, after some cleanup. The ground electrode is a loop of wire attached to the spark plug body.

Good score, those are interesting plugs for sure, and a brand I have not seen before.

Good news! A member of the Spark Plug Collectors of America contacted me on Facebook is offering me a Liberty spark plug with box to use as a pattern. :)

Glad you found a source to use for a pattern for the boxes. This makes me think of old toy collectors. For those folks the boxes are as valuable as the toys that’s in them! But that also goes for other small collectible items too.
Looking at the difference in the plug first pic and yours the take apart style must be the earlier style and then the company went to the one piece style. Interesting.

I've seen Liberty "Spit Fire" plugs in old gas engines. I don't know if the manufacturers are connected. Most of these I've seen had 1/2" pipe thread and various reaches.

I got the plug with its original box today. I scanned the box, imported it into Paint, then cut and pasted to fill in the few missing parts. Here is the resulting flat pattern .jpg file. You can print it onto good card stock, cut it out, and assemble it into a complete box. I don't know why some of the printing was blacked out, but it is too straight and clean to have been added after the fact.

Once I get some fresh ink for my printer, I plan to print up five new boxes and put the Liberty "Dome top" plugs I bought at Hershey in them. :)

Looks like they changed their address from Westfield MA to Boston MA at a time when they had an inventory of boxes with the old address. Makes the box and plug all the more interesting.
