Ok what do you guys thing of this as a first pass...

As far as the silver leads being rubbed off, a lot of the fingers on these cards (mine included) are gold plated, and silvered where the gold wasn't plated.
Also, the terminators for the thin traces on my layout are round, which I think is what I am seeing from the photos. I can't find any reference of circuitboards from that era (or any other) that have square terminators or vias at the end of those kinds of traces.
Most likely those spots are vias through to the other side of the board.
Is there ANY way we can get a better shot of the card?
Also, I think the topmost things we see, the short rectangle and the long rectangle underneath the clamp lip are actually thicker pieces than the rest of the card. These may be wedged in there to take up space? I don't know.
Also, in regards to the back side... My preference is to pick the new style we're looking at now for one side, and the idealized style, or current style we have for the other. Because that would be a valid card layout for the ESB Luke card. I know for a fact you won't be able to see through one side to the other, unless you're using a flashlight. And it means I can produce one set of cards cheaper for you guys in the long run.
However, I am not opposed to doing just the "new V2" on one side, and nothing on the back, if consensus dictates that's what people want.
