Hi Phil and thanks sending me the recent info about the 'Mag-Lite® C & D Cell Flashlights Repair Manual' now found at manualslib.com. This PDF is very useful...
Finding this type of OEM repair info on the Internet is often difficult since some 3rd party Internet search engines restrict and re-prioritize search results solely to benefit that company's corporate profits.
It amazes me how much interesting Internet info is restricted and hidden by large search engine companies in their blind attempts to increase profits by restricting search results.

Maglites without a D in the serial number are from before 1992. These lights are quite a bit different from the later 'letter serials'. The biggest difference is the size of the light. Non-letter serials have a much thicker body and weigh much more.
