I found these 3 on ebay. He's starting at a penny so not bad. Anyhow my pitfall looks nothing like this. He says its for 2600. But the 2600 pitfall I have is nothing like that. Even label variations this is all I could find.

I have the one that looks similar to those variations. Never seen the one in this photo. Perhaps its not for 2600 and he is mistaken.
