I am so glad that I found your blog, Chris! I was just gifted a typewriter by my husband's grandmother, who was gifted this typewriter brand new by her father (a typewriter salesman and repairman) when she graduated from high school in 1956. After some internet sleuthing, we've determined it to be either a 1955 or 1956 Royal QDL. We know exactly nothing about typewriters, but I do write for a living and thought this would be a fun project to clean up and use occasionally, maybe for Christmas letters. While Googling and YouTubing how to properly maintain and operate a QDL and all its very neat features, I suddenly realized that our font was different than what was being shown on the sister machines in the videos and pictures. This one's font is sans serif, charmingly "mid-century" looking with cool slants in the lowercase "e's."

So, lo and behold, I found myself here after Googling "royal qdl typewriter sans serif font," and sure enough, our typewriter looks almost exactly the same as the one you purchased (though ours has the red Royal emblem and no silver wings and is more of a battleship grey textured finish), and the typing example you shared is a dead match to what ours looks like! I had no idea that this "Vogue" font would be such a desirable quality. Thank you for sharing and documenting your collection so that people like me can learn!
