Advert Description
Please feel free to make an offer.
A very early, brass upper bodied spark plug by OLEO. I believe it may have a patent date of around 1910 to 1913, but please do your own research.
The Plug is marked "OLEO Magneto" & trade mark logo on the ceramic part.
Stamped "No 11A OLEO 20-11".
A nice example of a rare plug.
Unusually the upper most part is made of solid brass & the bottom steel.
In expected used condition for a item of this age & nature. There's a little minor surface rust on one side, the steel flat part that will easily clean up.
I don't see why it wouldn't still work, as the ceramic insulator's still in one piece. A three ground electrode design. The three outer & central electrode are still in place. It doesn't rattle & is solid. It's even got it's brass screw on the top to attach your wire.
It's approx just under 3 1/2" long.
Please study the images, as they also form part of the description & please do your own research.
Can post at extra cost. Postage includes being signed for.
