TAI HING, TELSALDA OR SCHUCO? THE AMPHIBIOUS MYSTERY

I saw this on You Tube.

Its clearly a T in a Circle / Tai Hing box.

But what make is the toy car?

It doesn't look like my Tai Hing/ T in a Circle toy car.

Is it the famous Schuco amphibious car that was used in Thunderbirds as a fire tender?

Is it something else?
