The planer head you pictured is made for the Festool 850 planer as an accessory. It's sort of expensive to buy especially if you need to puchase the 850 planer as well.
Some othe power tool companies used to offer a similar rustic blade system for their own planers. The other brands typically used the regulsr cutting head, with a special blade and possibly some type of adaptor insert.
I know i've seen the rustic blade inserts and adaptors made for both Bosch and Metabo electric hand planers. Milwaukee and AEG likely offered the same type of attachment, at least for the European market. I'm not sure about Dewalt or Elu, but at least Elu seems lkie the kind of company that might have offered that sort of thing, and the Dewalt planers were
Basically a made using the Elu design after Dewalt/Blank-and-Decker purchased Elu.
I'm not sure whether the rustic planer inserts for the above non festool powertool brands are still made, although I've run into examples on ebay so there should still be stock around. A number of Euro made planers are also capable of using other brands blades so it may be possible to use a rustic blade set in another brands plane, although the if the adapters are proprietary this may not be the case.
