Unfortunately, that's the problem with eBay you need to take people at their word but their are to many con men/ scum on it to make a quick few pounds...
You think you are doing the seller a favour as it can be their giving up due to illness, death of a person or giving up due to time restraints....you buy the items then they reappear some time later same description!!
You buy drawings as it says "built the model want to recoup some of the cost drawings no longer needed" a brand new set of drawings arrive and guess what a few weeks later it's back on...
Hulls for sale, a friend from englandshire bought one never saved that much on RRP it was a copy not a brand hull as advertised not even the same one shown in the pictures and it needed some serious work to fix, he contacted the seller to complain and was offered no replacement but to make him another hull from the selection he was selling he was challenged on this as the reason he was selling was giving up the hobby!! Don't believe he got his money back
Fittings that are clear copies of other peoples, fittings on now that are marked for a model yet it never had anything like them
Look at the crap on eBay just now, hulls and fittings that are really questionable,
I would strongly be very wary of buying from eBay unless you are sure of either who your buying from or can check authenticity of what's being sold
