[Healeys] How to de-seize a brass tap?

[Robert Duquette]

Hi!

I have a drain tap from my rad that is seized up.  I had to remove it to drain
the rad.

I've cleaned it up as best I can, but I'm nowhere close to getting it to
function.

So, what do I do next?  Try to remove that cotter pin without breaking it?
hah!  :)

Then remove that spring.

Then hammer on the pin that they came off of with a piece of wood?

But ... then there's still that broken handle.  How do I get that out?  I've
grabbed onto it with vise grips and twisted to no avail.  ( It's already
broken so vice grips seemed reasonable,. )

Do I soak the whole assembly in a penetrating oil or something?  I already
have, but, I could leave it over the winter.
