Are you by any chance a member of the Hamilton Model Engineering Club which celebrated 25 years in October? I passed through Hamilton 2 weeks before their 25'th anniversary celebration at the waterworks, but did get to see some of the models that were there, and of course the two beautiful Victorian beam engines that powered the pumps - spectacular. I've been hoping someone would post proper pictures of the exhibition.
Welcome to HMEM - there are great resources here.
