[TPIN] Bach Strad

[David Johnson]

Here's a question for the group.  I have an Elkhart Bach 37 that I bought
new in the early 70's (I paid $350 for it, brand new street price. 
Unbelievable, huh?).

Anyway, I am thinking about resurrecting it.  The valves are still pretty
good, but the leadpipe and bell are in need of replacement.  My question
is: What combination of bell and leadpipe would give me a more open blow
than the standard 37 bell and 25(?) pipe?  Or is that not feasable?  TIA
