Hello, collectors! Today we're looking at a true workhorse of the mid-20th-century American office: the Royal KMG standard desktop typewriter. Introduced just after World War II, around 1949, the KMG—which stands for Keyboard Margin Control—was designed for heavy daily use and became a staple in businesses across the country.
This particular machine features the classic grey crinkle finish that was so popular during that era, designed to reduce glare under harsh office lighting. One of the most distinctive features of the KMG, which we can clearly see here, are the 'tombstone' shaped glass keys. These keys not only look fantastic but were designed to cup the typist's fingertips for better ergonomics.
Looking closely at the condition, we can see it has certainly seen some use. There's noticeable dust accumulation, particularly down in the key basket, and some wear to the finish, including what looks like residue from a sticker on the right side of the front cover. While we can't test the mechanics from a photo, these machines are renowned for their robust, all-metal construction.
Because they were produced in such massive numbers, they aren't exceedingly rare, which is reflected in the market. I'd give this an authenticity score of 99%—nobody is faking these standard models. Assuming it can be brought back to working order with a good cleaning and a new ribbon, a conservative auction estimate for this Royal KMG would be in the $50 to $150 range. It's a wonderful piece of industrial design and a tangible connection to the analog age!

Assessment:
This is a classic example of a post-WWII American standard desktop typewriter. The Royal KMG (Keyboard Margin Control) is known for its durability and distinctive 'tombstone' keys. It appears to be in fair to good cosmetic condition, though it shows signs of use and age, such as dust accumulation and some wear to the finish. A full mechanical assessment would be needed to determine its working condition.
