Hello Dan,
When I first started working on CSX2079 the first thing I looked for was a foot box vin tag. I asked Tom if there was a tag. He told me in the 40+ years of owning 2079 he hadn't seen one. He said the number was on the latch and also on the front of the frame somewhere. I found the one on the latch.
I just made Tom aware of the ad for CSX2081 and told him to look at the photos for reference as 2079 is obviously 2 cars before. CSX2079 was originally a red car as well.
Regards,
