Oh Joe, that is so good to know. As I collect more of these babies I am surely going to run into this problem some day. Just got two new oldies this past week: White Rotary brown crinkle finish in cabinet 45X81196 (on bottom of base 9801-4.) And a blue Universal Super Deluxe. (F/0009 The only nos. I can find) made by Standard Sewing Equipment Corp. Japan. Does that made sense? Will post pics, am charging my camera battery right now.
