question about old spark plug

I found an old spark plug in the backyard where I found the other stuff, my camera batteries are not working right now so I can't post a photo, the bigger bottom part of it is rusted but the top white thin part is ok, it says "Leonard high compression, trade mark req, pat. Jan 26th 1932 on one side and has a number 1 on the other side. Does anyone know what this kind of spark plug was used for and when?

I found a couple of batteries with enough power for this 1 photo, it is hard to see the words cause of the glare but you can still see the shape, the 1 is on the other side.
