We received a query from Diane Kester at the Wayne County Historical Association & Museum in Goldsboro, North Carolina:

What do you suggest for old permanent machine? Here’s what we have.


Paul Bourcier, editor of Nomenclature 3.0 and Nomenclature 4.0 answered:

That would fall under Machine, Permanent Wave – a primary term under the sub-class, Hair Care Objects (see Nomenclature 4.0, p. 118).
