"Single shot revolver" refers to the Savage 101 target pistol.
This gun looks like a slightly smaller version of a Colt Single Action Army (Peacemaker) revolver. It does not, however, have a revolving cylinder. What looks like the cylinder is a swinging chamber block with a single chamber in it, making it, in fact, single shot.
These guns are not very common because the oddball design did not sell very well.
