The odd marks are proof and inspector markings.
Steelhead just bought a 4" Model 30, I believe. Very nice little pistols. A 2" with soft lead HPs loaded properly would be a very good house/desk gun, especially if you happen to have an elderly person with weakened hands that needs some home protection.
back in the early eighties, I gave a G/F a Smith .32 pistol. She used it to dispatch a serial rapist that targeted gals in the Parking lot of the State Farm office in Jax. Yeah, they can be effective. Killed that fellow graveyard dead.
