>see no reason given for us not to unify the handwritten symbol we have seen with BREVE ABOVE.
The map sample may have been hand lettered, however, there's no evidence that suggests that the usage is limited to handwriting. On the contrary, we have heard from at least one contributor that the symbol exists in a font used by a Landesvermessungsamt, which is a German geographical service on the state level, and in the context definitely a proper authority on usage.
In an answer to me dated September 26, the same contributor stated that the font Landesvermessungsamt's font from 1982 does not contain any combining breve glyph at all. The mail probably just didn't make it to the list:
