C1 Possible UNDISCOVERED Frame Markings Just Found??

[Justin B.]

I am disassembling a 1961 frame/chassis today. The car was a plain-jane, low option project car with nothing original on it. I can tell it has been raced due to some old roll bar reminents, a rear crossmember which has been filled with lead, and 1/4" pieces of "cut-to-fit" metal plates which were spot welded in both front and rear sides of the frames X member. I'm guessing for extra strength. After removing these metal plates, I noticed what appears to be original but aged frame paint with between 1 and three baby blue, vertical lines. These paint lines are in the back two X pieces with the paint lines on both sides.
I havn't seen or read anything about these lines but do any of you know anything about them? If I could post a picture I would but I don't know how. JB

they weren't on my 61 big brake vette when i restored it years ago. it was a Southern Va car all its life and the frame was in exceptional condition with minor surface rust( which may have removed the lines if they were present on assembly of the car).mike

They are "slash" marks like you see on the mid year frames. I will get a picture on here some how.

Those are not typical of factory production. They could be done when a specific car received additional testing, like the "pressure tested" stamping used on specially tested fuel units. What you have there would not be shim marks, because there is no body mount anywhere close to the X member on which the 3 marks are placed. They could also very easily have been placed there for some reason post-production.
I can assure you, having lived in San Diego for 11+ years and dealing with many 61-62 cars, that what you have is not standard factory procedure.
