Wow, thanks for all the reply's. I'm guessing that he just wants to check that it isn't stollen, I've had it for a few years now so if he was looking for 'his stollen one' he's been looking for a good while now. I bought it from a small local trailer dealer and I suppose I should have done the same check but it didn't occure to me.
Ifor williams do have a database of stollen trailers but as the auction end tomorrow then he's not going to be able to check with them before the auction ends.
Worst case mentioned above though is what I'm afraid of, I've never registered it as mine, until the last hour I wasn't aware that you could/should so if he was then to register it as his own etc etc
I have several trailers flatbeds stock trailers etc, all bought second hand but I have purchase reciepts for all of them, Monday I recon a phone call to Ifor Williams and get them registered.
Thanks for the feedback
Chris
