Two photographers taking pictures at a wedding

This picture shows two photographers who are taking a picture of a scene in front of them. I believe they are guests at a wedding and are preparing to take a picture of the happy couple.

As a vintage camera collector, I'm particularly interested in trying to see what models of camera are being used; I think the man on the right has a Praktica FX2 or similar with its waist level viewfinder being used with a magnifier, but I can't make out what camera the girl is using - anyone want to hazard a guess?

Although there is no date on this slide, the clothes the girl on the left is wearing suggests very strongly the 1960s.
