OK will try Remi (was talking to him about something else and never thought to ask - duh Mark) but before I commit to buying new, here is the pic.
This is a Gaastra cam that was on the sail and is identical to the Maui Sails ones
Gaastra X-cam.... gap where batten goes in is 40mm wide..... rear edge (where batten seats) to the rollers is 43 - 45mm
anyone got one (I am stingey and the sail is for sale so I don't want to spend too much on it if I don't have to!)
Also - I was going to try a Tushingham cam from an old sail and it would not fit. so from the sail I have 4 tush cams and a few tube/rod battens if anyone needs anything. It was a 7m "Airforce" which about 10yrs old
