Most tea pot carbs look the same.
55 tea pot did have the choke on the intake manifold, so no place to bolt a chock on a 55 carb.
Some of the Lincoln carbs are modified for use on E & F engines to my best knowledge.
One sure fire thing, the top body of the carb which has the chock butterflies for E & F, and like the Lincoln carbs, >>>that body part is taller than a normal/typical teapot carb. One other easy and noticeable thing, a regular tea pot has rounded edges on its choke butterflies, and the performance E& F & Lincoln has squared off edges at the bottom.
I have performance tea pot ones here, and a Lincoln teapot, for a few F's being worked on, only reason I know guys.

Is this the worlds first exotic automobile? The 1935 Harris fwd speedster, No heavier, higher, wider, taller or longer than an AC Cobra, but many many decades before.
