Royal Quiet DeLuxe Typewriter Complete Total Body Removal by [[The HotRod Typewriter Co.]]

Gerren uses a Weaver gunsmith screwdriver set for most of his screwdriver needs. [5:00]

On the newer QDLs two of the screws for removing the rear plate are accessible from the top underneath the carriage instead of all on the rear.

The screws for the front body plate can be loosened and don't need to be fully removed to take the body plate off of the machine.
