That exclusivity of yours exists largely only in your head. Here it is being sold by a reputable store, one of the best known folding bike sellers in the country with a brick and mortar store in the heart of the country's capital. They don't sell fakes.
Now, why one would want to buy that tire ($36) at that price or why Brompton would have a special deal with Schwalbe to make such a mediocre tire is beyond me. The only Schwalbes worth the coin are the Marathon Supreme, Almotion and Modial. I should know for I own several pairs and have toured on them.
The Marathon Racer in ETRTO349 and in ETRTO305 aren't on the official website of Schwalbe:
https://www.schwalbe.com/en/tour-reader/marathon-racer https://www.schwalbe.com/Marathon-Racer-11100289 the closest size is the 40x355 for the Birdy.
Brompton asked Schwalbe to make the wired Marathon Racer in ETRTO349 to replace the former Brompton Green tire which was also a cheap low quality tire.
Then Brompton asked Schwalbe to a make a tan wall folding Marathon Tire for the Brompton Explore special series. There are no more folding Marathon Racer available from Schwalbe (there was an Evolution Line Folding Marathon Racer long time ago which was a lightweight version of the former Marathon Supreme Evolution Line but it was discontinued).
