http://www.navy-radio.com/manuals-ttycorp.htm#m37 has a copy of "37
KEYBOARD SEND-RECEIVE (KSR) TELETYPEWRITER SET AND 37 AUTOMATIC
SEND-RECEIVE (ASR) TELETYPEWRITER SET FOR "DATA-PHONE®" SERVICE
GENERAL DESCRIPTION AND OPERATION", issue 1, dated June 1971
<http://www.navy-radio.com/manuals/tty/m37/574-301-100-iss1-7106.pdf>
which on page 7 has a keyboard layout diagram. It looks to me like the
second right, topmost key, at least on the illustrated layout, came
with ^ ~ RS.

Also 574-321-800TC, "37 Keyboard (YK) and Base (YB) Parts" (issue 1,
December 1967, linked from that same page), page 9 indicates that for
this you'd want key cap part number 314843, which is listed as ~ RS ^.
Judging by that same page, it looks like P/N 313040 might also apply.

This isn't as good as an in-person look at an actual unit, of course,
but it definitely looks like you at least could have a key cap with a
tilde on the 37.
