There’s a single copy on Keith Rucker’s site, but only of the main manual
http://vintagemachinery.org/pubs/12494/27936.pdf
Something odd going on at the moment accessing the site, both directly or via archive.org so good luck.
Re Bedroom Workshop; I’ve been trying to contact the owner for some time regarding access, and I also had a few documents which might have interested him, but not been successful thus far.
Does anyone here know Steven Vine?
