Double surprise
Just received the singer 99K that I bought last summer (long story) - in the box I received two sets of attachments, assorted bits including a long bobbin for a Singer 127/128, two different buttonholers and TWO (2) 221 manuals in nearly perfect condition! Now to find the machines to go with them!
BTW I don't have a manual for the 99. But it sews beautifully - I must have it threaded correctly.
