Bob,
Aha! Thanks for unravelling that mystery - that website is a perfect example of a great idea badly executed. First of all the index is tiny, repetitive and very dull to hunt through, then you have to fill your shopping basket, go to your email account, save the attachment zip file, extract the zipe file, then go into each file's folder to get to the actual skp component.... and then they're almost uselessly high poly! 😒 Many 3D download sites are moving towards drag and drop files into SU for crying out loud!
Still, I got a couple of nice accurate WCs which I'll remodel to about 1/10th of the poly number.
Thanks for explaining that to me,
