Quoted from tomdrum:I believe your wrong. My understanding of serial numbers is that #1 was serial 1001, #2 1002 and so on. So #2975 was the #1975 produced. See this and note not a single serial number under 1K. so I believe IPDB numbers are correct.

Look at others like Flash Gordon, you will never see a serial number that isn't 4 digits to start with.
Pretty sure this is correct. They all stared at #1001
