Thanks to everyone for their replies. Speaking as someone who DOES know a thing or two about driving multiplexed nixie and VFD displays (several hundred such clocks sold), I can now confirm that, if these items are not exactly "duds", they are NOT capable of being driven in a 7x9 addressable display format.
Grids 1 and 9 are internally SHORTED TOGETHER via a cross bar, which looks like it was intended to help in the construction and alignment of the display, with a view to being broken off before the glass seal was complete. Also, grids 2 to 8 are simply NOT CONNECTED internally! You wouldn't really be able to pick this out from the ebay photos, but it is plain to see with a display in your hand, and with an eyeglass. The eBay listing is therefore incorrect when it states connectivity to some grids. I have no strong opinion or even interest as to their origin, but they are date stamped in Russian with an April 1998 date. I suggest you avoid, while I attempt to communicate with the seller.
