Of those, as you've rightly pointed out, at least one more remains. What about Story & Clark? Astin-Weight?

Astin-Weight seems to have quietly gone out of business, see for example their Yelp page:

Story and Clark now apparently outsources their manufacturing:

This is a pretty common scenario. For example, Baldwin used to be a huge piano American manufacturer, and there are plenty of used American-made Baldwin uprights still around. They still make pianos, but as of 2008 they have outsourced all of their manufacturing to Asia.

Companies like Steinway and Mason & Hamlin also have similar arrangements, but only for their lower-end pianos.
