Thanks for all the kind remarks, everyone. I've now run out of photos worth publishing. Hope there's time to take some more soon. There should be something to report when I finally have time for the RPO project, but that may not be for some months yet.
Meanwhile I'm just back from a model show put on by my old club in W. London, which had 2 large scale exhibits - a one baseboard section of the club's own G scale layout, and an awesome private effort in Fn3 by a team of four club members, which must be about 40 ft long. So far it's been in development for four years and is now almost fully scenic, with only some buildings at one end to finish. Like a fool I didn't take a camera, so cannot regale you with pictures. However it's called the Orange River & Portland, so if you hear that it's at a show near you, do go and take a look.
