... I have contacted Centa who say the coupling is a tied to Morgan part and so can not discuss it with me. I have sent several mails to people at MMC but never had any reply.
That's disappointing, but not surprising. Perhaps some who have connections on this forum could provide a poke into Malvern. One would think they would want to engage with an enthusiastic user community who are doing development work on their product for free...
In any event, put me down for a set also!
