luvmytoolz is correct, their design was based on the old Holzher lineup; Holzher's handheld tool division went bankrupt in 2000 and was purchased by TTS / Festo; some tools were incorporated into their respective Festool and Protool brands.
Check out the Holzher 2350 trim router and its different bases as well, that might look suspiciously familiar too. Or the ZK 2340 chain mortiser.
