Thanks, Dwight.
Regarding your answer on the toggle, I can see what you mean. Handling and inspecting a 1900 provides a lot of understanding as to the nature of the improvements made to the 1906.
As for the variety of markings, it is apparent that, as more AEs are "discovered" , the knowledge of the range of markings, charactaristics and productions ranges is constantly changing. I have many of the books going back to Datig and see many updates (and contradictions) when scanning all the available information on a particular model.
