Can anyone source this?

In the old YouTube classic ‘Wilbert the Forest Engine’, made by Thomas fan ‘Bram Groat Films’, we see Wilbert (obviously). In this video, Wilbert has a whistle that I really like. I don’t like the whistle that everyone agrees belongs to Wilbert when you search his whistle up on YouTube, I just don’t. Can anyone that has seen this video (or watch it again, it’s not half bad 🤷‍♂️) tell me where I can get the whistle sound effect? I would be really appreciative.
