There are 11 or 12 different styles of puzzle boxes. They vary by age, style of closure (latch or spring), no (or has) thumb indent, included attachments, positioning of attachments, and how the attachments are held in place.
Regardless, all puzzle box attachments are short shank, and will fit your 66 , 27, 15, 201, 99. (I'm not sure, some of the hemmers may be bed mount in some versions). If you find one reasonable...$20?, it's a good buy. I think they typically sell for more, just because of the cool factor!
