Tim, it looks funny to me, too. It looks like the connector part (all the metal looking area) is sunk in too far. On all of my REOs, the SS rim of that part sticks above the colored aluminum a tiny bit...maybe 1 mm. It's not flush with the colored aluminum like yours appears to be.
I don't know if it will hurt anything or not....but after checking all my REOs, that's what looks different. It could be some new connector Rob is using?? I'd PM redeyedancer and simply ask him. Or....he'll see your picture the next time he pops on the forum and I'm sure he'll have an answer.
