The CD 236 is unlisted in the latest (2003) price guide. If you have a '99 price guide, you'll find it in there. It was dropped because it was not able to be verified. There is a paragraph in the beginning of the '03 price guide with a full explanation. Not surprising, since Brookfield power pieces tend to be somewhat on the scarce side.

This piece surfaced at a show, well after the '03 guide was published. I believe it had been in storage for some time. I didn't know exactly what I was purchasing at the time; I just knew I didn't already have one like it. When I got it home from the show and still couldn't identify it, I contacted Mr. Woodward. Woody was extraordinarily helpful and very pleased. He confirmed this to be a CD 236.
