Definitely not a rally, but yesterday I was privileged to visit this small private museum near Gloucester.
It's a sad story, the collection is being broken up and will be auctioned off at the end of the month.
'Enjoy' the report and, if you are within striking distance and your interest extends to include stationary steam make an efort to visit while there is still time...
