A detailed radial-velocity distribution for the supernova remnant associated with the radio source W1 is determined on the basis of H-alpha interferometric observations. An interpretation of the observed velocity distribution is proposed according to which the supernova exploded inside a patchy dust cloud and expanded into a partially ionized medium. It is suggested that enhanced H-alpha line emission is excited at sites where the supernova shell collides with dense cloudlets, this enhanced line emission would have a negative radial velocity in the compressed gas behind the shock front reflected from a cloud, but a positive radial velocity in the recessing part of the shell. It is concluded that emission from the approaching part of the shell is not observed since it is screened by the dense cloudlets.
