I did not know the word recorder (also) translates to "Blockflöte" in German. The principal difference is,that the clarinet has a reed (german: Zunge), other than the "recorder". The shown clarinet is from the age of Mozart.
I guess the reed makes the difference. There is also the Native American flute with a split reed that makes a very beautiful, somewhat 'haunting' sound.
Do we have a MANDOLIN? Similar to the guitar but - tuned in fifths instead of fourths, typically eight strings, higher pitch. Sounds similar to the Balalaika to me. Featured in Rod Stewart's Maggie May. Compare to the Balalaika in Mary Hopkins' Those Were the Days.
The medieval Handorgan or Portative Organ was replaced by the Accordeon in the early 19th century. However nowadays it is quite often built again as Journeyman´s Piece for the journeyman examinations of organ-builders in the german area. In Germany the vocational education is still very close to the medieval model.It is regarded as the base of our successful craftsmanship and industry.
I remember first time I saw and heard an electric guitar (1960-61) thought it was the craziest thing ever. Now everything can be electric - even drums.
