If you would like to have a matching set? It would help to post a couple photos of which ones you have. It may be helpful also to network with a couple other people interested in the number twelve Edison plugs as once a few people have a mixture of styles, they can swap styles around to the benefit of all.
The shape of the porcelain changed a few times through the several year they were being manufactured.

The 13s and 14s are the pipe thread that fits a model T. I don't know nor have a reference to tell me what the Edison number 12 fits. It could be the model A size or some other (18mm?) that fits some other car. Whatever the thread size and type and whatever they fit would help to identify and get what the OP is looking for.
I am just trying to be helpful.
