Info Wanted: Star Wars Radio Dramas - alternate episode introductions?

I am aware of a limited edition box set containing the A New Hope and Empire radio dramas that included alternate episode introductions. I think I have every piece of recorded work from the radio dramas except these alternate intros. Does anyone know where I can find them? Also, if anyone has a recording of A New Hope with the two scenes that were only in the initial broadcast, I would absolutely love to have it.

Many thanks in advance for any info you can offer.

Just uploaded them to Spleen.

They are probably small enough to send another way if you’re not a member there.
