in the East Anglia archive films website there a number of old wildlife documentaries. Going way way back. I did on one occasion provide a link to a silent film going back to 1955 about Minsmere and its wildlife. That sadly is not available to see right now. But there are other very old films still available to see free of charge for anyone to seee right now. But because of copyright it won’t allow anyone to post links and share some of those films. But here are a few photos of the films you can see going way back particularly in Norfolk. But anyone wanting to see these themselves will to do a search in the East Anglia Archive Films.
Regards,
Ian.
