Lionel HO Steam

Can anyone tell who made these for Lionel in 1964-5?
How does the whistle work? (Not the same as O gauge)

Are you sure about the dates?

Earlier than that Lionel had some models from Athearn and Rivarossi, later Lionel had models from Kader (Bachmann’s parent).

Specifically, which model are you interested in?
