Acquired 1946 Royal KMM Standard Typewriter (Royal Typewriter Co. Inc.)
Serial Number: KMM18-3015689
Extra-wide 18 inch platen with support "wings" and a 10 key decimal tabulator
Royal Elite typeface at 12 CPI and 6 lines/inch vertical
I purchased this 1946 Royal KMM standard typewriter on October 4th via Goodwill for $22.00. It’s equipped with an extra-wide 18 inch platen and carriage with “support wings” and a 10 key decimal tabulator which means in its day it would have been used for some heavy-duty accounting.

The logos could be in better shape, but the rubber feet and overall condition are pretty exceptional. It’ll definitely need a good cleaning and some very minor adjustments. Tipping the scales at 47.8 pounds makes this the heaviest typewriter in the collection so far.  $0.46 per pound isn’t a half bad deal for something in this condition. 

Can’t wait to do some restoration work on my second Royal KMM.
