A while back I was doing some research into the age of a bandstand in Bristol. It was for a work of historical fiction - I needed to know whether it would have been there at the time my characters were.
I stumbled across a really helpful website by Paul Rabbitts, which includes a database dating bandstands in the UK.
He's just launched a crowdfunder to publish a book on the subject, and I wanted to give it a shout out. You can donate to the project here.
