It’s curious that Perry recognized an antique electric car when he saw one, especially now that electric cars are making a comeback! There was a recent film about the old electric cars and their demise. Find out Who Killed the Electric Car? here or here.
+ What Perry immediately recognizes (from a distance of 6 feet!) as “an electric automobile” is a line-engraving of a car on the reverse of the 1-inch-diameter St. Christopher medallion that Della found in the baby’s basket. We viewers are given a fine close-up of the engraving, displayed in Paul’s open hand. The engraving is further ID’d by Antique Car Man (ACM), who gives some historical details of this 1915 or ’16 “Detroit Electric” car and a lead to a current local owner (Mrs. Kerrick) who still uses hers, which her departed husband built for her. We also see the actual car in two scenes of the episode. The engraving, some of the “facts” given by ACM and the glimpses of the car elsewhere in this episode correspond to an actually existing car: the Detroit Electric Brougham; read about it here! ACM gives the name of the hobbyist-builder of the car as “Leander Kerrick” and gives some details, a few of which seem to be drawn from the life of Henry Ford!

• Henry Ford was an engineer and Chief Engineer at the Detroit Edison Illuminating Company from 1891 to 1899. Ford and Thomas Edison had a long friendship.
• Detroit Edison supplied batteries for electric cars in the early 20th Century, including to Detroit Electric cars. Edison also helped Ford develop an electric starter for the Model T.
• Henry Ford actually did build two or more experimental or "hobby" electric cars about 1914.
• Henry Ford bought at least two Detroit Electric cars for his wife Clara, the first in 1908. Here he is stepping into her 1914 Detroit Electric Model 47 Brougham. Here is that car in 2010 at The Henry Ford museum.

Here, with some technical details, is a Model 31, which may be the model filmed in this episode (closing scene shows that the car does not have wrap-around rear-corner windows). Finally, here is a 1917 Model 62 - don't miss the last paragraph of the write-up (regarding the mystery novel)!
Contrary to the "about six" cars that ACM says Leander K built, Detroit Electric was the most successful electric vehicle of the Twentieth Century, with over 12,300 cars and 535 trucks being produced up to the mid-20's.(see here). I'm left wondering why this Episode's writer, Jonathan Latimer, didn't have Mrs Kerrick's first name as "Clara"! Submitted by Gary Woloski, 13 Dec 2011.

That is the BIGGEST four week old baby I've ever seen ... times have changed, it's more likely that a baby closer to that real age could be used in a tv show. MikeReese
