I don't like this sort of proposal. Different times, different standards.
When I was a yoof and did quite a bit of fishing, the British Records Fish Committee removed from the record books all kinds of fish records because they could not be sure, half a century or more later, that the records were as they said they were. To me, it undermined the credibility of the records. There were two especially well-documented pike records that went, John Garvin's 53lber (Lough Conn) and Tommy Morgan's 47lber (Loch Lomond). Even when Gareth Edwards (yes, that Gareth Edwards) broke the newly-recognised British Record with a >40lb fish from a Welsh reservoir, I couldn't get that excited about it, because I felt that the much older records of bigger fish were perfectly credible.
