I also have this book, Featherweight 221 and I. Yes, it is more $$ at $35.00. Can I say it paid for itself 2 times over, just yesterday. I had a thread stuck behind the bobbin case holder. With Dave's book I was able to take out the Gib screw and get the stray thread out, (and and tiny piece that has been this past year that I have my FW).
I know if I had to have it fixed by a repair guy it would have cost me at least twice what I paid for the book.
