Type 'Harrison 140 imperial threading' into Google.

Inter alia, it will find

and

https://www.mig-welding.co.uk/forum/threads/advice-on-lathe-purchase.62989/page-3

These may shed light onto your problem.

Most unlikely to have a 6cm leadscrew unless it has come from a dressmaking shop or is ex-Blue Peter.

These imperial tables for a 140 were all on the Harrison Yahoo forum site, I am sure I put some there, but it is all shut down now by the recent Yahoo policy. There is a new Harrison site and I will have to see if the files of reference data have been transferred across.

I will post my simple .jpg of information here in the hope that it is readable. If not message me with your email and I will copy it to you.
