I've never seen a manufacturer-original built-in
RS-232 adapter for them, at least not inside the 33 proper (the
keyboard-printer unit).
Not strictly Teletype, but there was a company called Data Dynamics who sold the Model 390
(IIRC). This
was Teleype ASR33 mechanicals (keyboard, printer/punch, reader) with totally different
electronics in a
rather nice metal casing the enclosed the paper and tape rolls, and which even had a
couple of little bulbs
to illuninate the printing. At least one verson of that did have both RS232 and current
loop interfaces.
