$5 bucks! You scored big!!!
My mother had a Mary Proctor. After she passed in 2002, and we cleared out the house, we left it in the basement (laundry space) because it was a bit rusty and "old". DUH! I wish I had that monster now! I could have repainted it and recovered it and it, too, had a cord-minder. A sturdy one!
I have a cord-minder on my 'newer' board but don't trust it to keep it plugged in esp. since a friend of mine had a fire in her house (not from the cord-minder) but from an iron that was turned 'OFF', but wasn't. Darn those electrical things!
Needless to say, I unplug every time I leave the room.
