I think the PCB cut off at ebay # 300628220912 is an image artifact. If you look carefully you'll see the "cut" extend into the gray area on the right. Fluke-L (it's "L", not i) wouldn't foist a sawn-off board to sophisticated buyers.

It's not paranoia if it's true! :-)
Take a look at the pictures for # 270725678037 . These boards don't
have the connector cut off of the corner of the board. Good eyes.
