KGT set on eBay:

I've no connection with the seller. It looks like a bargain.

Too late for this deal, but wow. People who watch eBay for stuff like this: roughly how often do deals/lots like this one get posted there?

Lots of interesting go stuff is listed on ebay. However, I would argue that this listing was pretty rare.

Of course, you have to trust the seller, but it is unusual to have such authorative info about the goods from a reputable (second hand) seller. It is somewhat rare for stuff of this quality to be on offer with reasonable assurance that it was in fact what it was.

Usually stuff is more generic, or older and in poorer condition, or with more vague descriptions of the items.
