    Aesthetically I like the look of my two tone Olds Studio Nickel bell flair on the brass bell, but there is a sort of ugly red tarnish on the inside of the bell which is pretty noticable against the Nickel silver. Is there any good way to polish or clean that?

    would brasso be worth a shot?

    Probably, I don't know(is that abrasive). Seems like it will be difficult to polish it, and clean it up after wards.

    Red seems like a strange color for tarnish on nickel silver. I'd start with a non-ammonia cleaner and a soft cloth and try to clean it off. I wouldn't graduate to abrasives like Brasso unless the horn is unlacquered.

    It is two tone. The bell flare is nickel silver(no red color), but just behind it the bell is brass which has some red tarnish.

    If there is any lacquer inside the bell that you want to try to save, I'd use lemon juice to remove the tarnish on the brass. If there is no lacquer, or you don't care about any remaining lacquer, there are plenty of polishing compounds that will remove the tarnish -- 3M Tarni Shield Copper & Brass would be one.

    lemon juice? Sounds like a worthy try.

    I'd give the horn a bath after the lemon juice -- citric acid is pretty mild, but there's no sense leaving any down inside the bell crook.

    I just stripped a lacquer large bore Selmer Radial and polished it up with one of these

    and some metal polish. It took less than an hour to polish the entire instrument. It's made of foam and works with a drill. Low speed, some polish and a microfiber to wipe the residue and it was the easiest polish job I've ever done.

    Did the trick. I had to add a little salt. I rinsed it out after wards.

    Still some discoloration, but it isn't red so I claim success.
