They look similar to the cams I had in my R8's. The one for the bottom batten was ground down on one side so it's easier to get on to the mast (I think). Was that one in your photo from the bottom batten?
Thanks guys, just wanted to eliminate and make sure of what was stock standard. It (pictured) came with a 2nd hand R6 OD 6.2 for some reason, but I've a few spare R5/R6 cams waiting to replace it.
