No you didn't miss it. I'm trying to find which church has the one with the lozenges on. If it's Tully Church then I'll have to dig out an old picture I have of it as the original is now in a wharehouse in Trim.
There are two (apart from Tully) that I've not seen yet at difficult to reach churches, the lozenges could be on one of those. I have to check out one of these this weekend if I can get to it. The other is in a Chav-ridden estate somewhere and I never feel like leaving the car to look for it.
