Hansli says none of his current inventory has any adulterated case hardening. Oh yes it does. He has a lot of listings around on several different sites, but here's two on GunBroker that have been ruined by this hack: 57252140, a nice Brummie built hammer gun, and 57252151, a nice Francotte 16. The leopards spots are still there, it seems. What a shame these two nice guns are added to the many he has ruined with a gas torch.
