Q: What can you tell me about my electric percolator? It not only makes coffee, but can toast a slice of bread at the same time. The attached metal plate says, “Armstrong Perc-o-Toaster Model PT.” What is the age and value?

A: The Armstrong Perc-o-Toaster Model PT was made by Armstrong Electric and Manufacturing Corp. of Huntington, W.Va. The company was founded in 1899 and made table stoves, electric ranges and other electrical appliances. Your combination percolator-toaster was first made in 1918 and was still being made in the 1930s. A waffle-iron mold, which could be inserted after removing the toast drawer, was available as an accessory. A 1931 ad in the Saturday Evening Post claimed the Perc-o-Toaster could also cook bacon and eggs. The base of the appliance was made in different finishes, including nickel plate, black enamel and white enamel. The price in 1931 was $11.85. Perc-o-Toasters today sell for about $200. However, the appliance can only be used with its original cord, which has a non-standard double-plug arrangement.
