yes very true when an unidentified machine RAF was shot down or damaged it was recoreded by the staffel or Greuppe and Geschwader recorder as a Viermot or 4-mot. 4-mot or viermot was used in the pilots flugbuch and was written in either way.

Viermot was also used for Day time bombers especially US heavies more as a grouping when attacked Viermots or Schwere pulks, Dicke Autos, etc ......
