Thanks for the link to that article. I love coffee and tea pots and coffee makers. That article didn't mention the Regal Easy-Flo 4-10 cup, 600 watt, no. 7581 coffee maker we use. This would have been made after the Regal Ware company was incorporated in 1951, but well before 1968. I wonder why this wasn't included in the review.
I would have used a paper filter in the Proctor-Silex...we do with our Easy-Flo. That Proctor Silex is so mid-century cool looking..must try to find one, though they never show up at the thrifts I've visited.
Good collection, Petek!
