A man of the cloth and the steel he wields

Royal Model 10 Standards, Dual-Glass, Single-Glass and No-Glass – when did it happen?

Weapon of Choice: Totally-not-a-Royal “Einstein” the Silent Atomic…


Whatever Happened to the International Typewriter Appreciation Month?

The 1940 AMES American Typewriter Parts Catalog

The one that started this hunt, the first known Model 10 Royal:
From the Virtual Typewriter Collection of Evan Pitman:
1913 Royal 10 Serial #X-173084

First Dual-Glass:
From the Virtual Typewriter Collection of Drew Saffell:
1915 Royal 10 Serial #X14-226176

Last Dual-Glass:
From the Virtual Typewriter Collection of Richard Mohlman:
1923 Royal 10 Serial #QX 696203

First Single-Glass:
From the Virtual Typewriter Collection of Ryan August:
1923 Royal 10 Serial #X-754246

Now, if we compare this one to an example after 1197537, can we see a difference in the glass panel?

From the Virtual Typewriter Collection of Adam S:
1928 Royal 10 Serial #X-1204198

Other than the glass bevel perhaps being a little thicker than the earlier version, I don’t immediately see a difference. Perhaps between 745309 and 1197537 the single-glass panel was a little thinner than the later version, and is not listed because the later version is a drop-in replacement? Anyone want to measure the difference?

Anyway, after that little bit of research, I’ve updated the Royal Serial Number Page:

Happy I.T.A.M.! :D

  1. Quite interesting. I noticed an earlier Royal some place without the glass panel I thought the glass panels got removed and lost or broken during the life of the typewriter. I never noticed the thickness difference until you pointed it out.

    I’ll take your books for typewriter appreciation over a typewriter post for ITAM.
    Those books are great assets.

    I almost always forget about ITAM. A few years ago I was reminded very early in the month by other typospherians posting about it. I do not need a special month to appreciate my typewriters. I appreciate them each time I use one, especially my Hammond.

  2. This is a fine example of research, drawing on first-hand experience of real machines, important old documentaiton, and modern digital collaboration.

    Every month should be an ITAM!

  3. This is one of the first things I looked up, when my wife gave me her grandma’s dual-glass model that turned out to be from 1918. She’d gotten it used, for a secretarial class. I had noticed that there were other glass configurations and had only gotten a very general idea of which came before or after, but this is much clearer.
