Gerd, I was one of the folk who bought some of John's kit in his great workshop clearance.
He moved house shortly afterwards, and thus lost his BT email address, so I unfortunately lost contact with him.
I did join Home Model Engine Machinist a while ago, specifically to contact him, but he was last seen there in Oct 2020.
Dek, Thanks for that info, I hadn't realised John was still with us.
If you are still in contact with him and Wyn, please pass on my regards to both of them; he might remember me as as "Bill from Buxton". (White van, White Disco, and the Marlin in my avatar)
Amongst many other things I bought his high speed drill press and 5C collet setup.
Persevere with Facebook, there is some good stuff there if you're selective enough.
Regards
Bill (on FB as peak4, the same as here.)
