Uh, Walt, the frame is primarily cosmetic, holding the mat down.  It
could easily be brazed back together, or even left as-is.  Of course,
if you braze it, you'll need to re-plate the frame _or_ paint it with
silver-chrome paint, as plating is expensive.  The rod could easily be
made up using the other side as a pattern from a piece of steel rod.

It appears the broken side was bent from something, as it doesn't match
the other side well.  It wouldn't be hard to make it with a vice,
hammer, a small torch (even a plumbers torch would do) and a die set to
thread the end.  If I lived closer, I'd make up a rod for you.  It just
needs to mirror the good side.

My little small parts plating kit might even be able to plate it but,
once again, silver-chrome paint to the rescue -- depending on the level
of restoration the piano is being given.  The pedal frames are often
found cracked like that, by the way.  I haven't figured out why, as
they are pretty securely fastened to the wood pedal block.
