Actually, that lighthouse doesn't look quite right for a reverse J. I've looked at my Freeman's 102, 105 and 106, which are all reverse J, and the lighthouses all taper downwards into a slightly broader base that yours appears to, Bruce. Seems more akin to the lighthouse on reverse H.
Probably an optical illusion, but even so. Be interested to hear the thoughts of others on that one.
I'm not sure about the rock.
