Thanks, Doug!
I really appreciate the time and effort you put into posting these!  That is a very rare cabinet, about which not much is known.  Even with photos, it's still not possible to tell if it's really all wood or if it's vinyl over a substrate.  The striping in the finish is not a clue, because Singer did that with its real wood cabinets.  And it's still not known if this was offered for the Athena, or if it was a later development offered when the Touch-Tronic was introduced.  
The lower pulls on it are the same ones that are on my No. 266-1 Swing-Away.  
Again, thanks.
