No they just kind of resemble some Ronals I owned once (Which were called R-15's, but this is not them) but bought them second hand. They could very well be some other brand but the center cap style with the lock screw is identical to my old Ronals. German almost certainly, Ronal likely.
They could also be Avez or Borbet, all have some overlaping styles.
