    I was looking at a sextant on ebay (not in my price range), and I noticed a couple of things on the certificate.

    It suggests using "German batteries or American AA with a drop of solder on center +". Could someone explain? Are German batteries slightly longer than American AA batteries? Is that the idea? The grammar isn't 100% clear here; do we add a drop of solder only on American batteries or any batteries? Does this work effectively long-term?

    Also, how long was C. Plath part of "Litton Industries"? That was new to me.
