Thought I would post my reply to your email here so others might see the info as well...

There's actually one more variation that was used recently. The card with the longer line at the bottom on the reverse is actually the earlier card. The card with the shorter bottom line is the newer card. The newer cards originally had the "Club Victoria" on the front ending 4mm from the right side of the card. As such the punched hole removed part of the text. They moved that text slightly left on the very latest cards so it ended 9mm from the right so it wouldn't get punched any more. That appears to be the card in the scan. The intermediate card that had the text further right was only used for a very short time from what I was told the last time I was there.
