At first glance the pistols look like S&W DA32's, but there were several companies making lookalike models at that time.  They could also be H&A, Iver Johnson, or others akin to the famous Grace L. Ferguson Airline and Storm Door Company as immortalized by Bob Newhart.  The cylinders of these two in the picture seem to have an extra long cylinder stops at the back end of the cylinder which was not, I don't think, on the actual S&W models.
