Matt,
I've found these in some odd places... The Hubbell duplexes I described above were in an old 1900's house we razed the old system out of... Most common place I seem to find the single ones were in the FAU closet of old 1940's & 50's houses. My old elementary school I went to had some really strange stuff (Sierra Nema 5-15/6-15 duplexes in the bathrooms!) But each classroom had a single 5-15 recept & one of the style above in a 2G box.. always right next to the door.. & one step up of the same in the cafeteria.. I've no clue what the purpose of alot of things in that place was for!
