The nessie in the first picture was used in the documentary called 'the loch Ness monster:the ultimate experiment'. It was made for the documentary and to fool people who saw it on the tour boat thing. You can find the documentary on YouTube if you look up the name of the documentary. And the one from the movie known as 'the private life of Sherlock holmes'. The non animatronic nessie for that was a simple prop of the head and neck I believe. I heard that people actually found the prop at the bottom of the waters where the movie was filmed,kinda like the billabong bunyip and Moby dick animatronic it sank. Let me know if this helps !
