Imitation really is the sincerest form of flattery it seems.
The similarities to the Tak FSQ106 cannot be ignored, because it's downright copied
At least SW had the sense to make the focuser a direct copy R&P, wisely deciding not to put a slip-o-matic Crayford on it

Be interesting to compare them side by side with the FSQ. Price really is not much different either.
