Does anyone have any info on Prince Barnu of Coventry 1960's?

Hi!

I've come across this website after looking up my granddad Freddie Barnes aka Prince Barnu, who wrestled in Cov in the 1960's?

I have emailed the site and hopefully they'll get back to me, but thought it was worth seeing if this catches anyones attention!

Interested into seeing anything, I sadly don't know much about him.
