As to the Henney, unless and until information surfaces permitting closer identication of these, this will also stay 'as is'.

I had found similar entry for a similar example from 1939, where the Model Number had been entered as '1701A' and was gonna suggest something, but quickly back-pedalled when I saw that there are no commercial chassis shown in the Clipper parts book. While BDeB's info shows several models available as chassis-only, I'd hate to even venture a guess without additional factory documentation - like the parts book for those 20th Series 110-120-160-180 non-Clipper models (at a minimum).
