Help ID Gillette Blade Banks?

[Bobbers]

I am trying to figure out what these Gillette blades banks go to or about what year. As some of you know in 2016 our area had historic flooding. I have been slowly trying to reorganize my razor collection. Right after the flood I did a quick sort, throw out what could not be saved and separated the rest in a half way organized fashion. All the blade banks got mixed up. Any help would be appreciated.
