The upper hammer is for a Crosman 38c or 38T air pistol. Off the top of my head, the trigger is same. Air pistol parts.

They are powder metallurgy parts, and harder than the hobs of heck to drill or file, but cheap to produce.
(Heck, finally something here that I actually know about. sorta)

The mainspring vise could be anything from a bonafide antique, to a modern made tool for use with any lock that uses that style of spring.
