New information to add to this always appreciated.
Note that some models such as the M5,M4, etc, had both early 2 bolt & later 4 bolt air cleaner flanges and some models also had 4 lines of information on the "L&L Manufacturing" side while others of the same model had 3 lines. The "Langsenkamp"line was dropped in early 1940, so if the carb has 4 lines, it is pre-1940, 3 lines 1940 -up. Also note that some models such as the M74 & M74B had both early and late body castings and these castings overlap, and the M74 had 2 types of number stamps, early was centered, late was in the same location as the 74B.
I have a complete list of what body castings were used on what carb models and will post one of these days when I am really bored.

L&L DC Model carburetor applications - NO LONGER LISTED
We are a bit fed up with all the nit picking feedback over DC carburetor applications concerning what model fit what model in what year and had what needle & seat, etc. Due to this we have pulled all DC application data. We do apologize to our customers around the world for this, but enough is enough. A lot of experts out there with opinions and we have enough else to do without having to constantly argue over DC carbs. The application info was only posted as a guide and a favor from our experience anyway, and we always felt that the customers had a good idea of what they wanted and needed, and were quite capable of making an informed decision.
