underlever spring source?

[Michael Spalding]

List,

Suddenly I have 3 pianos all of which (whom?) need either a few or a set of
underlever springs:  A S&S with some badly mangled, and two lesser makes
which left their factories 75 years ago with fewer than they should have. 
I've looked in Pinaotek and Schaff for either replacement springs or
suitable spring wire for bending my own, but didn't see anything.  Got a
source?  Other ideas?

thanks

Mike
