Top of my head, i don't know the precise location where they were located before they were acquired by the History team, but I believe they were purchased off a guy that ran a 'carnie' business (not intended to be derogatory) like Chant's or Wittingslow or something (not them specifically, but companies like that - the name escapes me). As you can see from my post above though, not every carriage was obtained, as they had previously sold them off one by one.
Dom, you're absolutely fine. Apart from a few factual inaccuracies in your video (which we could have helped with) and that you hadn't actually asked to use them - Everyone quite liked what you'd produced. We're not vigilantes, and we don't hold grudges. We're all about everyone's love for the park - and wouldn't deny anyone wanting to visit. you're welcome anytime... join us for a beer, hey?
