I'd love to see someone continue this project. I'd send him an email and see what's what.

If you do manage to get hold of it, keep us informed as to the progress.

As an aside, I seem to recall that these engines were not that hard to find using one of those junkyard search engine sites. Probably not much of a market for them.
