Hoping someone can point me in the right direction. We moved into an old house and have been gradually doing it up, I got round to replacing the light switches this weekend. There is a hall light and landing light on 2 x 2 way switches on the same circuit. The hall switches always worked on both lights but the landing switch would only ever operate the landing light. My dad had a bash while I was out but has managed to balls it up and now we have no reference to how it previously once as a guide. I've put it together as per the image but have only got one of the landing switches operating the landing light and one of the hall switches operating the hall light. The diagrams I've seen show 2 x 3core running between the switches but I don't seem to have that much, just a bridging wire in the landing switch. I think it just needs bridging correctly but any help appreciated.
