Thanks, Mike. Yes. These are identical with what you show above. There are 
six of these, all packed in their original boxes, and the 6 boxes are then 
packed in a single fitted carton. I have no idea where the SK could have 
gotten them.

I have also recently found several different offerings on the eBay's of some 
European countries which are asking "interesting" prices for a pair of used, 
tested ones. In France, for instance, the asking price is 500 Euros.

Used ones are selling for between $150 and $200 each.

I'm sure the SK's children had no idea of their value.

I am not surprised at either their value, or the fact that the heirs knew nothing 
about them.

Thanks again,
