Looks to me like it has two (2) safety valves atop the boiler, although it does appear that one of them is missing its lever arm and weight.
What it doesn't seem to have is a whistle!
Perhaps I should add that it does appear to be spitting a little from the port where the whistle should be, though not nearly enough to account for not having the weight pushing down on the valve, but even so, a whistle at full blow will not keep an engine from running at that same time.
Ah, so my bad, I was so fixed on the missing lever that I missed the spring loaded SV. 😎
Still, your observation as to how he could keep steam up without the lever arm and weight is perfectly valid!
I have to assume he had some sort of a wedge block stuck inside the hole where the whistle pipe should be, but I did notice that there was always a bit of bubbling coming out of that hole.
