This is a picture of a 1941 Chrysler Thunderbolt (picture sourced from google search).  I was leafing through the May 1952 issue of Motor Trend I was just given and spotted an ad in the "Sell 'n Swap" section.  I had never heard of a Chrysler Thunderbolt as the only Thunderbolt I've heard of (up to this point) is the 427 powered one by Ford. 

Here is what the ad said:  "Chrysler Thunderbolt built by Chrysler at a cost of $10,000 in 1941.  One of six experimental cars, original throughout, 20,000 actual miles.  Will sell or trade.  G.E. Prime, Eugene Oregon". 

WOW, so Chrysler built six of these and some or all made it into private hands and roamed the streets.  Gotta say, that is pretty cool.  Can't imagine what something like that is worth now.

Lots of other ads for Duesenbergs, Cords, the odd '32 Roadster, a one cylinder 1904 Cadillac, an engine from a Tucker, several ads of people wanting info on repowering their Lincoln with a Cadillac engine, one person selling Ardun heads, the odd early electric car, someone selling a steam car with 16,000 miles on it.  I can't even imagine a steam car having that many miles on it.  Plenty of interesting stuff here ..... can't help but wonder how much of this stuff (if any) has survived to this day either in museums, private collections, or covered in 70 years of dust in some dilapidated single garage.
