A few weeks ago I had a post on my acquisition of the 1978 Saga Dave Kingman disc.
Kong's position is incorrectly shown as 2B, while on the BigT version, he is correctly shown as OF-1B.
I also found an auction for a BigT disc that looked like this...
...showing the incorrect position. I assumed that there were two versions, and I immediately bought the 2B disc.
Unfortunately, this is what came...
...with his position as OF-1B. I emailed the seller to find out what was going on. He was confused by my email and called me. I explained what I was expecting to get, and he said he'd check into the situation.
Later in the evening he called my again. It was bad news. He made a mistake with his listing, using a Saga picture with 2B instead of the BigT picture. It seems as if there is no error version of the BigT disc.
So here is the scoop: If the position listed is 2B, you've got a Saga disc. When it says OF-1B, then the disc is BigT. There is no corrected Saga disc, nor an error BigT.
