Can't be answered without a DETAILED description of ALL markings, barrel length, finish, grips, sights, box, accessories, papers, condition.
Yes The model 10 is a 38 special revolver that may be cocked for single action and also operated in double action by trigger pull alone.
No serial number provided.
Depends, A "Single Action" revolver, such as the Colt Peacemaker, carried in the old West, DID have to be cocked before each shot. A "Double Action" revolver, such as a current day Smith & Wesson, does not require that the hammer be cocked- it CAN be- or the trigger can be pulled, and the hammer will rise and fall.
