Angle of attack on a helmet that has period paint on it
My gut says, if it has that much paint on it, leave it. But do you think there is a way to get rid of the rust? This is hypothetical, since I don't actually own any helmets. I just wanted to see what the responses are going to be.

I’d treat the rust that was there, rather than try to remove it.
This can be accomplished using warm water and teabags. Find a container deep enough to immerse the helmet in, fill it with warm water, then dump in a pack of teabags. Give it a stir, then dump the helmet in. Leave it to sit for five or six hours, then fish it out. Either leave it in the sun to dry, or seal it in a container with silica gel packets to draw out the moisture.
It’s a very simple chemical process. The tea contains tannic acid, which reacts with any active rust and neutralises it. The result is an overall darker appearance, but if you dry it properly, no new rust will form. I have used this method on a couple of relic helmets in the past, including one lake-retrieved lid that was very ‘crumbly’. It works surprisingly well to stabilise even far-gone relics.
This isn’t just useful for helmets, either. Any metal item showing signs of active rust can be treated in this way.

Without seeing the whole helmet it's a bit hard to tell but often these relics are often treated to an acid bath by the seller.
This one however does not look like it has been treated. Hard to tell.
The acid bath (search the forum) will remove most of the rust. Usually leaved the paint a shade lighter. I like BB's less invasive recommendation better.

I never would have thought of that in a million years, thanks for the tip!

Oxalic acid might be an option too.

Sounds likes a shocking abuse of good Tea BB. I don't suppose you brew it up afterwards?

A bit of rust doesn't hurt the flavour at all. You can really taste the history!
I'm joking, of course... Or am I?

Good point.
You know, 18,000 people have died of the flu last year entering into this year. Only 3,000 or something like that died of corona virus. Hmm....
