When I read your post, you got me thinking.
I thought I remembered seeing that patent date on the globe in one of my Little Wizards.
However, when I found the lantern, the globe has two dates.
The 3-10-14, and 2-18-18.
Date on the lantern itself looks like 23.
I don't see an "S" before the 23, but it's a little bit larger than the other numbers, and it's the last number in the series of dates, which starts with FEB-?-98.
The middle column came out stamped on the vertical rib of the tube, so I can't really make it out.
