What was the name of Charles Lindbergh's airplane in his historic first nonstop solo transatlantic flight?

The plane was built by Ryan Aircraft in San Diego which is the reason for the naming of the San Diego airport as Lindbergh Field.

It's hanging in the Air & Space museum in Washington DC. I saw it a few years back. It's such a small and rudimentary plane. It's a miracle he made it across the Atlantic. I would suggest to anyone visiting that museum. If you're into airplane history, it's a must.
