Sarabella,
The 66 was very likely in the treadle cabinet, I have 2 older 66 machines 1910 and 1916 treadle machines. They sew very nicely. They're not hard to learn to use, just different than you're used to using.
The 1st photo is the 1910, its in much better condition. 2nd photo is the 1916, the finish is alligatored but still sews well; was lots more work to get it sewing again. They share a "franken" treadle, it has Elgin irons by The Free and a top from a Singer coffin top treadle that had a broken pitman rod.
