[Ltru] Any information on SF?

(That's not "San Francisco" or "Science Fiction", or any confluence of the two.)

We're in the process of updating to the new IANA registry, and I was cross-checking to http://www.iso.org/iso/iso-3166-1_decoding_table. The code 
SF stands out.

Transitionally reserved
BU    Burma     
CS    SERBIA AND MONTENEGRO     
NT    Neutral Zone     
SF    Finland     Not in IANA. CLDR maps to FI??
TP    East Timor     
YU    Yugoslavia     
ZR    Zaire     

I had first presumed that SF is not included because it was withdrawn before RFC1766. But SF is not even listed in http://en.wikipedia.org/wiki/ISO_3166-3 as a retired code. (ISO makes it exceptionally painful, as we all know, to get access to 3166-3: http://www.iso.org/iso/country_codes/background_on_iso_3166/iso_3166-3.htm). Note that http://www.iso.org/iso/iso-3166-1_decoding_table definitely
has some oddities. For example, instead of "officially assigned", for
two items it has "officiellement attribué". So for all we know, SF is just a mistake in that table!

Does anyone know more about the code SF?

For comparison, here are the "Exceptionally Reserved", two of which are obsolete codes.
