John, I just remembered in your introduction you mentioned you had a Boxford Lathe my memory also is they are related to our Hercus Lathe so I enclose a pic of my Hercus are they alike in any way? Also thanks for your pm when the shouting and must be attended to is under control here I will follow through with my offer of info etc.
Kind regards Peter. PS Parts removed during a clean up of my lathe made in 1967 in other words on other days covered in swarf etc.
