Thanks for the welcome Tony, I will try and post a picture I assume you mean of the Lister and hope that I get it right. Sorry all I could manage for now is the whole unit, the pictures of the Lister were marked as invalid so I will try tomorrow. By the way I forgot to answer Pauls question what model ERF, it's a 1966 A series LV with a Gardener 150 and David Brown box.
