Hi Rob,
Thanks for the reply, I think the key words are "I would happily have another" and "the main parts went together well", both good reply's to an average builder not a super star like quite a number of here. It would be nice to get my reverse alphabet filled in, having built a class C, working on a B so just the A to go. Not sure where to go from there but an NER class M would be nice just it wouldn't really fit on a branch line but I have a broad imagination.
