Need strange lower distributor cap ID

[pgerhardt]

During the winter, when it is too cold to work in the garage, I enjoy restoring model A parts in the comfort of my warm basement workshop. So I picked up this "lot" of distributor caps for 20 bucks on E-bay to play with. (picture 1) One of them was strange. It had very large brass connectors on the "wings". (pictures 2-3) They look too big for the brass ribbon connectors that serve as plug wires on the model A. I am thinking it might be for a model A tractor using more modern plug wires? Any ideas on what this is?

After market. Looks like the terminals screw off for better connection or could use modern style wires. I am not aware of any Ford tractor that used this style cap/body. Nice collection.

They look like the tops to the "A" spark plugs that have been adapted to the distributer top.

I'm with Ray in La Mesa on this one. I run across this conversion occasionally. The threaded spark plug terminal are often twisted on very tightly with a pliers and may appear as though the cap was made that way.

Cap made by Renner's Corner, takes modern style wires

They look like the cap that came with my Miller OHV setup, because it has a different plug spacing. I junked it because I used a Mallory distributor or I would post a picture. The cap by Renners corner looks like a modern distributor cap.

Here's a similar one.

The one I bought from Renner's Corner, the one that is on my engine right now, is just like the one Bob shows above.
