Estate Sale find of the Day

My find of the day this week is this Singer Featherweight tray, Singer Zigzagger attachment with extra stitch patterns and various feet.
I can’t imagine why someone would separate the Featherweight tray from the machine case. I will probably need it someday. The zigzagger is like new with the instruction book. The feet / attachments include a ruffler, slotted binder, gathering foot, adjustable hemmer, rolled hem foot and backside seam guide. I like to keep a separate set of feet with each machine I own, so these will come in handy.
