I have not searched everywhere yet, but is there any Hayter enthusiasts here?
Sooner or later you will find a Hayter (enthusiast) !
Sorry couldn't resist that, what did you want to know? I'm o.k. with some of the history side of Hayter, but if its technical there are plenty of guys on this forum who can help, ask away?
Should be ok. With machines from the1950s through to 2012.
