You probably have a Mk. I pistol, manufactured circa 1958. If this is the case, it would be a semi-auto pistol, chambered in .22 Long Rifle.
If it is a semi-auto and made after 1957 it will be on the frame. I.E., Model 39 or Model 645-2. If by pistol you mean a revolver, you will have to open the cylinder and look in the recess where the crane/yoke rests.
