Jeff: Sorry for my late response but I was trying to check on my info. Yes, you are right and the white and blue cars are different... I stand corrected! The blue car, your grandfather's, had incorrect headlights in the old picture and also on the color pics showing it two tone blue, and you can see on the restored pics, now black and silver, it does have now the correct headlights and emblem.... or could it be i am still confused and it is the white car now restored? Mmmmmmm....
Anybody interested in the marque should get the book mentioned: "Elcar and Pratt Automobiles, The complete history" by William S. Locke.
About these two cars, Bill Locke's book mentions the following stories:
The two tone blue car... your grandfather's...
"Serial no. 39511
Elcar 8-81 - 1926
Glenn Brown of Hutchinson, Kansas, traded his airplane for this Landau Roadster when it was almost new and kept it for 60 years. The car's original owner wrecked the plane the day of the trade. He was not seriously hurt but was unhappy about having traded his car. It is currently on display in the collection of the Reno County Historical Society in Hutchinson".
About the white one, using your numbers as stated behind the pic, the books says:
"Serial no. A6S30
Elcar 8-90 - 1927
One of the cars that remained unsold at the Cutter Agency after World War II. This Landau was used to pay an agency debt and then was bought by the author in 1950 with 13,000 total miles registered."
So, again, my apologies but there are two different cars and I am confused now as to which is which... I will try to check with Bill Locke... he will surely be able to solve my doubts.
