I just got a 1950 version of this KMG this week in medium rough shape too. (My 7th Royal and my 2nd Standard)

Looks like a Royal KMG with the Henry Dreyfuss glass tombstone keys in Gray Frieze paint. https://typewriterdatabase.com/Royal.KMG.72.bmys

Mine has some minor carriage issues that I'm hoping clear up with some cleaning. Otherwise it may need some tools and internal repair work and/or parts. If yours is generally working, a good cleaning and oiling should get you going: https://boffosocko.com/2024/08/09/on-colloquial-advice-for-degreasing-cleaning-and-oiling-manual-typewriters/

Manual of the prior model KMM which preceeded it, so the functionalilty should be almost exactly the same: https://site.xavier.edu/polt/typewriters/RoyalKMM.pdf (Royal Standard internals were almost exactly the same from the Ten (1909) through the FP/Empress (1966).)

Home Study Course in Typewriter Repair and Service: ca. 1959, published by the Typewriter Repair School in Little Falls, New Jersey. Focuses on the Royal KMM among others: https://site.xavier.edu/polt/typewriters/homestudycourse.pdf

Searching on YouTube for cleaning and repair advice should help out a lot. Phoenix Typewriter has some solid videos on related models (search also the Royal X (ten), KH, KHM, KMM, KMG, HH, FP, and Empress which are all roughly the same internals with slightly different body styles.)
