I've been watching this GB, getting more and more twitchy, 'cause I wasn't 'in'. I did have a Takom Grant lined up, but, with the vagaries of evil-b and the RM, it never arrived. I'm not out of funds on that one so, only time lost ...

Note that the Ram bogies are heavier and more robust than the Sherman versions. The return roller brackets are a different design too, being angled rather than flat.
(As far as I know, there were at least three different styles of return roller used on Sextons)
