Hi Dave
The Wot is in the database with an ICAO code of ZZZZ, meaning that it hasn't got a specific ICAO code. I've hunted on the ICAO database and can't find one either, so I'm afraid that even if there was a silhouette, as things stand it would never show.
However you could change the database entries for the two aircraft there from ZZZZ to something else, like WOT, and then the silhouette would be shown. I don't do standard ones, but here's a photo version.
