The first one of Battery Point looks like a fairy book story picture doesn't it? The photo of the 4th order is good,but of importance is the lantern assigned to this Fresnel on the shelf. I just received operating instructions for it,too bad I'm not there to tinker with it. The window looks like it's in the radio room,can't be sure,the last one was the knee killer,up and down it all day. Thanks Bob,but I have a few more than that to share when I get home. Frank
