What is that emblem?

While at Back to the 50's, I saw a 1953 Chevy four-door sedan (or it
could have been 1954 - I can't remember) that had a gold script on each
rear door above the stainless trim that spelled out "Two Ten." I had
never seen the name "Two Ten" spelled out on a Chevy, including that year.
The unrestored car wore its original paint and the script was similar
to the Bel Air style, so I know it was original (though it needed
restoration). Have you seen this before? I sure wish I had
taken a photo, but my camera wasn't nearby.
