There's a chart in my copy of the parts book that lists all 
distributors with Type 3 applications for the purpose of showing what 
part numbers superseded others over the years. All the distributors on 
the advance curve page were used in Type 3s. Distributors with 111 part 
numbers seem to have been original to the "N" models.

111 905 205 L (ZV/JU 4 R 3) is for single carb engines from August 1963 
through July 1964
111 905 205 M is for single carb engines from August-November 1964
111 905 205 N is for single carb engines from December 1964 through 
July 1966
341 905 205 (ZV/JCU 4 R 3) is for dual carb engines from  August 1963 
through July 1964
311 905 205 D is for a dual carb engines from August-November 1964
311 905 205 E is for a dual carb engines from December 1964 through 
July 1965

The way I read the page, the two center charts are separate advance 
curves for the centrifugal and vacuum advance mechanisms within the 
same 1964 1500S distributor(!), which did indeed combine both types of 
advance. The 1965 and later distributors are noted by Russ' chart as 
having #3 retarded.
