I think it will make an excellent paperweight on my desk, would it be considered sacrilege to buff it all to bare metal except for the blue tip and red band ?
I was also thinking I would get the white stenciled parts redone in vinyl after I polish it.
I tend to be a bit of a traditionalist when it comes to such things...
If I owned that shell I would leave it as you show in your pictures, but look at some type of overall matte clear coat of an oil film that will prevent any more corrosion. This way all of the letters, marks and the like are original! If you "re-do" anything then you are removing the true nature of the item, destroying the history of it forever: please don't do that. Please?!? If they are at all rare or not, it doesn't matter, any 'refurbish' is destruction... but that is only my opinion.
Again, my opinion is to preserve its current state for generations to come, do not refurbish or alter it.
