(I am hoping this topic does not violate the rules of this section. I did read the notice.)

A Google search suggested that someone found some of PD's tricks in a barn, but I'm wondering if any of his props were actually collected and archived, along with his library. I suppose the lovely Debbie McGee would know, but I don't know if she has told anyone. Anyone?

He was selling some of his apparatus on EBay.

There is a huge storage shed on the current property.
If you search YouTube Paul Daniels video's, he shows his workshop/storage.

Does anyone know if Paul Daniels published any of his illusions as plans?

I'd love to know more about where Paul's illusions went also. Over his very long career, there were so many illusions and effects that he performed and several very unique props as well.

The illusions that were in a barn belonged to a magician in Tenby, South Wales who had been doing a theatre show in a theme park there. He had bought many of those illusions from Paul Daniels. Included was George Grimmond's Triple Trunk Escape. All of these illusions have now been bought by Chris Cross who lives in Newcastle, England and runs a number of magic businesses. Chris also recently bought the entire collection of Derek Lever and Taurus Magic. In addition Chris recently produced a new book about the magic of Jack Hughes.

In the meantime, as far as I know, Debbie has not undertaken any disposal of Paul's collection or library.

Has anyone ever put together a comprehensive list of all of the illusions that Paul performed in his career?

Wouldn't be surprised if Copperfield were hoarding them in a warehouse somewhere.
