Hi all.
Matt, it seems to me the same as my LEO 46, a chinesse copy of the OS 46 SF (the same for the 40), with true ABC piston liner assembly (bought 2 of them some years ago in Hobbiking at 36 USD each......

The LEO 28 btw is a good powerplant for Super Clown or Rigmaster type models.....
Reasonably well made, the worst part are the bearings, but this is easy to solve.
Almost impossible more for less.....

Kind regards.
Manuel.
