Who said it was case hardened? Its not case hardened. As I said earlier, you cant blue 'Winchester 94 receivers from this mid-seventies period as they are made from a different alloy (unless you iron plate them.) They go purple. Meanwhile the barrel is not made of the same metal and is blued normally.
After this they started chrome lining them, and that was even worse, because it would flake off. You couldnt blue them either. Then in the late eighties and early nineties they went back to blueing the receivers normally.
its a hunting rifle...not a safe queen or a range Barbie.....paint it and be done with it.... hammerite is awesome stuff.... harder than hobs of hell and looks good,sort of like grannies meat dish.....get your minds out of gutter....
of take it to gunsmith and get it reblued properly IF THEY SAY THATS CORRECT....
75/15/10 black powder matters
You have a 'solid black finish with freckling' - and that's straight off the internet.
The originals had that too, you just got a lot of 'freckling' - you lucky bastard
Never seen a 'case hardened' barrel, or even a pretend 'cased' finish on a barrel, or even a B/A reciever come to that - but those slab sided actions often got 'tarted up' with them - so I expect it might be cosmetic.
And 'johnduxbury' might have got it right - might be nickel steel which can make it difficult to apply a quick 'finish'.
Haha top blokes the lot of ya.
Either sweat (most likely) or blood has been left on it and it has rusted away. Just my thought.
Depends on your budget
Post '64 Winchester M94's have investment cast receivers and will not take conventional blue, coming out a horrible maroon/purple as has been previously mentioned. The factory iron plated the receivers before blueing and the patchy finish is where the very thin plating has worn or rusted off. Your best choice is to get it professionally Ceracoated, although it will still work perfectly well as it is.
I have an old 80s copy of shooters bible somewhere with the opening article being a feature on the full history of the M94. It goes into its different production iterations including of course the changes made in 64. There is also mention of a receiver that started being produced in the 70’s that “defied rebluing”.
Many of the 94s seen for sale these days are almost without blueing on the receiver at all. Yours has more blueing than most.
I believe the loss of blue from these receivers gives the rifle a rustic look of utilitarian usage that suits it and without affecting its performance.
The best thing you can do is get out and hunt with it, carry it by the receiver and the freckles will be smoothed out. In due course it will look like a proper gun.
just to throw another option in the mix, you could also just keep a sharpie in the cleaning kit and use that for touch ups at the end of the day.
