Re,

>Didn't know that periscope lenses got that big!

I got one from Alan Gee a long time ago, from a WW2 Japanese sub, the lens
is 5.8" dia f20, made by Nikon, infinity corrected, and at least as
good as a shorter fl apo. It was 1/2 of the relay system, the other half
was a 6" f7 triplet. The f20 will eventually become a gude scope.
