Hi,  just wondered if anyone out there has any clever ideas on how
to free up tuning wires on the reed pipes of a Wilhelm Bruder Modell
77 organ.  The wires do not seem to be rusted, but are stuck solid!
I have tried heating them slightly to make the metal expand, hoping
when it cools it will be a little freer, but no luck so far.  Luckily
there are only 17 Trumpets.

The Trombone pipes are quite different and have a much thicker tuning
wire, more like a rod.  I think they will be easier.

Any help would be appreciated as I don't really want to replace them if
I can help it, as other than being stuck they are in great condition
and not rusty at all.

Thanks,
