identifying nickey cars, and yenkos, and...

[black69]

he said something about hole in the core support and thats how the guy knew he built that exact car when it was new. I did not go and look for it as i don't have a nickey car, and had my 2 yr old running on fumes in my arms. the topic came up when i asked if it was found locally and he said it was in california when they suspected it was a nickey car. then he volunteered the builders marking put on them that were 'not' supposed to be on them. he made mention of the mark near a rivet but can't recall in relation to what. I am more interested in whether all these cars are marked or tagged in a hidden way as step one, and if so, how they are marked is step 2 (topic for another day if step 1 is true).
