Why don't you ask the seller and see what his response is.
Maybe he doesn't want anybody to copy the serial number !

I've been looking at an oscilloscope on eBay. Seems real nice. It isn't
the deal of the century, but seems better than most. But the seller has
taped over or blocked out the serial number on all the pics posted. Other
than the thing being stolen, what other possible and logical reason(s)
could there be to block out the serial number?
