I would not want to shoot it.
Are you sure it is not made as a "starter" pistol and made to shoot blanks?
No ejector rod, the trigger screw retention inset, the large hammer, the lined barrel (looks like it was added after manufacture), the cylinder looks like the same material as the frame (and that looks like "pot metal").
Absence of manufacturer's name has me thinking that the manufacturer was ashamed of it and did not want to be identified if the dern thing blows up.
