I'm the Wiz, and nobody beats me!
In the 2nd group picture the first White fendered piece has a shifter mounted near the head tube in the standard location. The 1st picture on the ferry the NW pictured has the shifter center on the top tube. The beach shot has the derailleur bike with the shifter center of the top tube. So the sailor is riding the other NW, not Jan's mother's NW.
