What I meant was from all the Gottlieb pins released in 1971 this is the most common by far. These are the replay Gottlieb pins released from 1971 (haven't added export or add a ball models). Also it's estimated that only 2-10% of games survive...very sad

What a good year 71 was Tony. I often wondered what the estimated survival rate is. 2-10% wow, that makes what we own really special.
