Definitely not any import Rogers set I've seen before! The lugs are the typical style used first by Pearl and ending up being used on dozens of import drum brands over the years. I've also never seen that style of tom bracket on the bass drum of any import Rogers offering. I honestly can't say if this is a legitimate Rogers offering, or is someone went through the time to add that "R" to the shells and the "Rogers" bass drum logo.
If you're happy with the sound, that's all that matters. I just hope you didn't pay too much for these drums!
