Does Leopard record your Mac's serial number anywhere (logs, etc)?

Question

I recently sold an old Mac, but would like to pull up its serial number. It occurred to me that I have a full clone of the hard drive.
Would the OS have recorded the boot-device's serial number anywhere? I breezed through the log files, but couldn't find anything.
Any ideas?

If you bought that old Mac, new, you may have other options
for getting the product's serial number from an old email or
other receipt from sales, service, AppleCare or other source.
Products bought online from Apple's store generate an email
receipt and also paperwork from the transaction should have
the serial number.
A clone of the software on an external hard disk drive should
not have recorded the information from the original computer
since that would've been supported by the Mac's Firmware.
That data is not normally in the hard disk drive; though it is
available to System Profiler, probably on demand when run.
Someone technical may be able to substantiate the path
the computer takes to display the information stored in
firmware when the software displays this during inquiry;
and IF any hidden data may have survived the cloning,
where it may be found. I doubt a clone would have the data.
If that were available in the clone, so would the firmware version.
As that is generally in the same location the serial number would
be saved. A clone can boot an identical hardware version of a
computer it was made from, and it "knows" to show the current
serial number and technical data from the new host, in Profiler.
So, that data is probably as distant from the Clone as the Mac.
You may be able to contact the new owner and ask, for your
records (having transferred ownership & responsibility) to get
the serial number and reaffirm the date of transfer, too. - You
should have made out a bill of sale including the SN just in case
the computer became a hotbed of illegal yet traceable activity!
Lucky you, if that were so, it'd likely be traced via internet, first.
{Just kind of kidding, there.}
Or check with the place you bought the computer from to see
if they may have a record of the transaction or have better ideas.
Apple sales support & AppleCare would be likely, if new to you.
My newer computers had email receipts and paperwork in boxes.
Good luck & happy computing!
