Prototype W2 heads 700$

Not to hijack this thread but is Bob still around? I'd love to pick his brain for an hour or two.
I have not seen Bob for years. I went by his old shop in Carson and they said he was long gone. i saw the clay models in his garage from early designs if the w2 head and other heads that never went into production. he had a flow bench in the garage. the first one i ever saw.
