Thanks a lot for those replies. Today I came up with some more details, including 2 videos and some pictures.
Some details from the brochure:
Engine power: 74 hp
Fuel pump: Simms
Loaded weight: 5690 kg (about 12550 pounds)
Tires: 7.50 x 16
A video where that sound is audible - though this one recently had a restoration and sounds a bit denser

In this one the sound is higher pitched and exactly the same as I mentioned

Lastly, I managed to find the engine serial number of a Turkey based Bedford, it is “861657”
Can we confirm that the engine is indeed Bedford 220? If so what could be the main reason for Turkey-assembled TKs to sound that different?
