Rainer, James, Philipp0408, et al:

I'm fully aware of "unter" and "uber"........

I got the "Unterwasserzieloptik" from:

[www.pastfoundation.org] (page 2) and from:

htp://www.pastfoundation.org/U166/WreckPhotos2003_2.htm (page 2)

Then I got UZO - "UberwasserZieloptik" from:

[indigo.ie]

The only thing I can do is call it "Uboot-Zieloptik" and everyone is happy......... :-))

Cheers,

ROBERT M.
