Hello again Paul,
Tony is not an easy man to reach, I think he ignores email routinely maybe because of the spam and malware it seems to attract
If you go back to his website he does have manuals and other printed material on Lang Junior lathes, go to his pages on machine manuals and seek information on Lang Junior. I have no idea how helpful it might be to you but he does ship worldwide. His manuals are good quality, digitally reproduced on decent weight paper with drawings you can easily read; I know this from experience.
You were seeking help from Chris Wells–the surname is actually Mills and you found his thread earlier. I think it most unlikely he would have coughed up £55 for a manual so what he is referencing I don't know. He is not an engineer, more a dabbler and collector of old machinery, all of which is in various dismantled stages to add to the collection in two garages at his mother's house in Somerset. None are operational and I dread to think how they have been "stored" there.
Chris and I fell out over his almost constant demands on my time to fix things he had taken apart, it was becoming too much to cope with. I last heard he and his partner had moved south to Romney Marsh to undertake a two house self build on land left to her after her father died. He promptly locked horns with the planning people over flood risks, having spent money with architects for drawings that were still to be approved. A more unsuitable man for full on and demanding practical work would be hard to imagine, so how things are going now I don't know.
I hope you find what you are looking for
Regards Brian
