Replace "Top Hat & Cane" alto bell?

I have a Buescher 400 "Top Hat & Cane" 400 alto. I've had it for years, but haven't played it for a while. I took it out of the case and found the pin broken off the octave key. I wasn't the one who had put it away and someone put it away without a top cap. In any case, got that fixed and had the horn aligned (nothing else). I was thinking of trading it for a bari, but after doing some research I realized that this alto had some problems. First, it had obviously been relacquered at some point, as the etching was a bit indistinct and, worst of all, the silver "Buesher 400" was not on the bell. Also, (and I was aware of this from the beginning), it was obvious the sax had been dropped since the bell rim was flattened (just a little) and the brace is pushed into the bell a bit.

In any case, with all these issue with the bell, I'm wondering, has anyone had any experience with replacing the bell on one of these? Are bells (or parts horns in general) even available for these horns? Is there any techs in the LA/Orange County California who could even do this if it were possible? Thanks for any help.
