What would be really interesting would be if they had any information as to where they were all stolen. Or at least some of them. I'd guess that's not something they can find out unless the owners somehow miraculously get in touch. Good police action. Sadly, from experience, most of these will probably end up being auctioned off, unless, say, they were all stolen in Bedford and it's easier to contact theft victims or for them to hear about it and contact the police.
