This is another example of not to get caught up in the hype that Vectis generates around itself.
Lovely pieces there, but there is not one that could be considered rare. All of those will have been up for sale in multiples over the past 12 months. If you want to buy one, set yourself a bidding limit and stick to it. If you miss out, another opportunity will be along soon for these things and you won't overpay.
Last auction. I missed out on a trilogo boussh. It went for £160 ( if memory serves ) plus commission. A week later I picked one up of the forum, as good if not better condition for £135.
That boba sale has flushed hundreds of mocs out of the woodwork. So many vectis can't keep up with the sales. There will be a lot more of these up for sale soon.
