Extinct Caslons?

I'd like to kindly ask for your help with a question. Surely some learned member of this forum has the answer. 

I'm a huge fan of caslonic type. Huge. I collect them compulsively--can never get enough of them.

I've learned that there are two versions of Caslon that I've never come across. One is a beautiful small-text cut of Williams Caslon. It works excellently at size 10 pts and below. A good sample is on Luc Devroye's site (scroll all the way down; under the red heading that says "Now Playing: The Butler"):

I really love it. Does anyone know if it's for sale anywhere? 

Second, it looks like the late, prematurely-departed Justin Howes used to have a website where he sold, years ago, versions of his revived Founder's Caslon that ITC never acquired/sold. There were about four of them, very beautiful, as everything he did. The website used to be here:

But, it's gone now. I was wondering if any copies of his defunct Caslons survive elsewhere on the internet. I saw a scan of them, some time ago, and they were wonderful. 

Thanks much in advance!
