Windom was the gun show of 
diggable boxes. Seems everyone in Minnesota  decided to tidy up the gun room and  peddle the detritus to gullible 
outtastaters. 
TeeHee. I am please to enjoy a few  castoffs of  
Lutefiskia
 An excellent 1981 air crew sheath knife, $3 including a light patina, now removed to reveal  Camillus 1981. I had assumed the makers spoke Oriental.  It was part of a package deal with a  Kabar USN Mk 2,   same price, The K  has  PTS as bad as you'll ever care to see,  evilly pitted with marks barely readable and about half the leather rings missing. This will become the base steel for a custom.
How 'bout  .452  --  230 grainers FMJ, 100 for three bucks,  loose in a baggie from a seller who said he sorta thought they were for a  .45 but wasn't sure.  Also two factory .257 Roberts  at $10 per box. This caliber is getting a little hard to find.
The Queen of the Hop is Miss High Standard, a  pumper in perfectly fine shape  save for the remnants of a Bubba varnish job. At $75 I'll always find room for a spare 12 gauge.  
Couple other goodies, but this is probably already more than you want to know. 
I can't offer you an interesting Windom history fact  because there isn't one.
EDIT: The prices in general were unremarkable, about the same as we've become used to, but I think everyone selling has become much more willing to negotiate.
