That's unreal !
We had a bad flood a few years ago , several friends homes went under and some firearms were not recovered for 3-4 weeks out of the wet mucky water...none had rusted as bad as that hammer... I shudder to think of what the insides looks like .
Most of the flood guns cleaned up with some light surface rust on blue finish , stainless steel revolvers came through even better .
Looks like some type of rusting agent applied to hammer...not simply a little water ?
