Robmck:  There have been sans-sarif fonts though.  My Coronet Electric that has that font is from the early to mid 1960's.  There must have been other manufacturers who had it also.

Where to begin?  A lot of vintage film cameras from Minox to 4 X5 field cameras with a lot of enlargers and other darkroom equipment.  I have also collect vintage stereo with turntables, reel to reel and a lot of amps. vinyl and CD's.  Some pocket knives.  Waiters corkscrews.  Slide rules.  Bell telephones.  Coleman lanterns and stoves.  I started with typewriters in the 1980's before it was cool (and expensive.)  At 73 I have come to a point that I have to start downsizing. 
Uwe and anybody else, let me know what camera you are looking for as I might have it.  

I don't collect firearms but I have an extensive collection of cameras too.  I also started collecting old slide rules, waiters cork screws, vintage stereo stuff and and a few old Bell telephones.  I bought my 1st typewriter, a SCM Classic 12 in 1983...that's about the time I got into cameras as well.  I don't need any more stuff so I have resisted collecting fountains pens.  Oh and I have two cats!  
I think I passed the test for this group.

I have always been under the impression that modern Japanese typewriters were the first to popularize this simple yet very efficient way of lifting the vibrator on the key stroke. That may be wrong.  I have two Brother JP-7's  from 1975 and 1978 that have this.  I also have an Olivetti Studio 45 made in Spain that has this from 1972. I did some brief research through Google and there may have been some early patents in the 1900's that address this but I am really interested in which company developed and popularized for the masses and when.  Does anyone know? 

Thanks Pete for the clarification.  What confused me is that one of my Brother's(Sear's Achiever),  a JP-7, from 1978 so much resembles, at least in function, your Brother Deluxe 1613.  Granted not nearly as pretty but I buy cheap and want a functional typewriter.  The Achiever has full variable Tab function.  It has carriage lock on the left.  It lacks a paper guide that yours has.  The ribbon color selector is different in that your machines red color is on the top of the selector while mine is black.  
I also have a Brother Deluxe 750TR , also a JP-7 from 1975 that has the fixed tab stops...also the carriage lock is on the right side and also has no paper guide.  No rubber rollers on the bail either.
Both are good typers for being lightweight.
