Just brought back the top plate for Emily, I did some modification---drilled hole for bubble level. Contributed idea by Walter, drilled hole on Byron top housing, I found that Emily should have one too.
bubble level is rather thick, but thanks to the plate, it is implanted quite well
Ok, what else we need?
Kids has just re-watched Harry Potter movies, said this camera should be named "Mad Eye Moody".
Worth to think about it.
