A 3rd XV in the Early 1960s

The first of these photos came from Jim Gathercole and the remainder from Robert 'Spon' Hodgkinson.  Spon's photos are marked '3rd XV' but so far we can't pin the date down as the faces in the photos don't line up consistently with the team members listed in the College Magazines for the early 1960s.  The 1961/62 season can be ruled out because several of those pictured here were in the U16 Colts that year, so the guess at the moment is 1962/63 .... unless you know different!

Looks as if Brian 'Brough' Porter is about to pull someone's head off. Colin Shreeve is directly behind him.  Brough was in the 2nd XV 1963/64.
This could be a practice or inter-House match because College players appear on both sides! Tony Dew, Colin Harvey and Michael 'Waz' Arnup are on the left.  In the line-out are Len Gosling (?), Michael Cullingham, Ian 'Bog' Robinson and Roger Postle (?).  Mr Naylor could be the referee.
Can you identify anyone?
Perhaps Brian Farrow towards the back of the line-out.  Colin Harvey on the far right.
