Drove over to check out this frame and fork on a italian made bicycle. I am doing my inspection, and notice nothing like a serial number on the bottom brack shell.

I look over the entire frame, and no serial number. Frame look like a Casati from the 90's but wonder if serial number are an american thing.

Frame was not the size I was told, so it is not a big deal. But I have gone to check out a few used bikes, and would a paper trail on ownership, serial number sometimes make it to police data bases on police report of stolen bikes.
