We present the results of imaging and scanning Fabry-Perot interferometry of the cometary nebula GM 3-12 (RNO 124) and Herbig-Haro object HH 376A. The nebula is cone-shaped with the star IRAS 20359+6745 at the apex, straight walls and two probable helical arms. HH 376A is the bow shock structure in the collimated high velocity flow, directed by the axis of the cone nebula, with shock velocity about 70-80km/s. The spatial and kinematical separation between bow shock and Mach disk in HH 376A was not detected, which makes this object similar to HH 111. The Hα profiles in the vicinity of the source are double peaked. The high velocity component can be attributed to the collimated flow.
