Here's part of an email received today, and we have confirmation that this was the Fishers.
I don't know how much you've been following this, but we've uncovered about 300 French Catch matches from 50s-80s from the INA in France. We're slowly reviewing them on Segunda Caida and posting them unlisted on youtube as we don't want to be cut off if we find more, though the collection is out there through certain channels.
One of the match we've uncovered is this really remarkable tag from July 19, 1957 where I think it's Charlie and Arthur Fisher vs Roger Delaporte and Guy Robin.

I wanted to bring this to your attention since I'm sure you'd be interested and could corroborate that these are the English team in question, and also because of how great the Fisher family archive on the website is. I don't know how much footage exists of them. I don't think there's a ton online, but if the family is interested, it'd be great if you could channel this youtube link back to them so they can have another piece of their family's history.
Thanks for these links
