Tapes/DVDs of British Fighters

[Sean Connolly]

Does anyone know where I can get tapes or DVDs of either John Caldwell or Freddie Gilroy, both British champions in the 1960s. Caldwell fought Eder Jofre for the World bantamweight title in Sao Paulo in 1962, so one would expect that a film of that fight, at least, should be available.
Also, other British fighters of that era such as Brian Curvis and Terry Spinks would be appreciated.
How is it that it is so difficult to get these fighters on film; one would imagine that the BBC would have a lot of footage from that era that would have found its way into the hands of private collectors.

That should be Freddie Gilroy
