Indeed. I've never seen any proposed reason for why the manuals use  
"bristo".  One possible reason is that the tool in lists of tools and  
parts would be shown as: "Wrench, briso., hand." or some such form  
with an abbreviation.

And military manuals use the word "alinement" not "alignment".  Either  
way, I understand what to do.

Maybe that is from the idea that if you touch the buss bar, it buzzes  
your finger.  Electricians of old were not as safe as most are now.

If I remember correctly, at one time the Navy, and possibly other  
services too, taught basic electricity with the idea that the current  
flowed in the direction of electron movement.  So, the positive  
terminal of a battery would be shown with the  current *entering* that  
terminal.  Then, there was a reconciliation with the rest of the world  
and all the training materials and schematics and so on got changed.   
This likely was before WW-II: I don't have any examples of that  
convention.
