Hi, I just purchased what I thought was a passenger set of cars for an early thirties blue streak for restoration. The cars are in terrible shape and they exhibit many poor restoration attempts from years of abuse. While stripping the paint ( automotive spray can enamel ) off the cars, I noticed that the insides of each of the 617, 618 and 619 cars was coated in what I thought was silver paint under the blue. Come to find out, its chrome or nickel. It was clear that this was never a blue streak set. So please tell me everything you guys know about the silver streak set. Did the silver streak set come with a three passenger cars or only two? The Greenberg guide only shows two, but there is chrome or nickel on the inside of all three cars. Thanks for any info
