Hot Blueing

[pgavey]

Hey guys need help here, I had a 1977 Win 94 hot blued a few years ago.
The barrel came out awesome, but the receiver turned a mauve /purple color. The smith said it was due to the material in the receiver, Have anyone here ever heard of this? It's very unique and I like it, Just surprised at the outcome.
Sorry I cant post pics here but pm me if you would like to see some. thanks Phil.

winchester used a different alloy on post 64 rifles...the only way to do them properly other than paint is rust bluing
