Televised Rugby Union I'm Trying To Get A Copy Of A Welsh Rugby Union Cup Final, It's Not On Sale Is It Possible To Access Archives?

I'm trying to get a copy of a welsh rugby union cup final, it's not on sale is it possible to access archives? - televised rugby union

The competition was then when the Principality Cup, which was broadcast on the BBC's well known, but a copy does not seem to sell. Is it possible to apply for a library file somewhere? Any help is welcome thank you, I do not want to think for myself, but for someone who would have great importance in a particularly difficult time.
