It will be so disappointing if SPF end up not meaning anything. Just some random way of saying Sir Proud Fop, or skinned proud fop. And what the heck does he mean by "Everyone gets skinned'??
I feel your frustration. Just one of many weird phrases that may or may not mean anything. Like "Full-tailed four-legged ship" or "Adam out of Eden"(!?)
Someone once mentioned there is a Sweet Pea Farm on MDI, but I question the use of the name of a local business except as an inside 'joke' or a nod to a friend. Not anything to do with the solution to the riddle. Also, something one would have to research to discover. Not exactly information found in the book.
I did find that SPF means Specific Pathogen-Free mice in the context of mouse research. Jackson Labs has a large facility on MDI. It is a biomedical research organization that works on disease, pathogens & genetics using specially-bred mice. I read about these 'SPF' mice on the Jackson Labs website. But this reference seems even more unlikely than Sweet Pea Farms.

Personally, I'm not convinced it does says SPF. If you look really, really closely, the bottom of the F is at the fold of the flag which could obscure part of the letter. It could just as easily be SPE.
