That is an interesting chart at the start of this thread and I am in the process of doing an article on Australian 30mm DEFA ammunition lots and dates for ACCA Journal .
I have over 70 different lots and variations plus banding and case finish types.
I will not post info here as it is an unfinished project.
The mention of HE loads by MF I feel is wrong as Australia used combat rounds from MR France from at least 1966 to 1970 as I have found fired HE cases and pulled projectiles of TP .
I do have a HE fuze but not sure if Aust. made or French. No internals or marks.
I have never seen an Australian HE or HEI load. Only the usual 2102 TP Practice loads.
Lot 6 from 1970 is my earliest lot and 23 70 is the latest I know of from 1970.
It seems Australia did not make Air to Ground (AG) trials till 1982 and also cases marked AUS instead of FR. Then went back to FR marked cases until 1984, my latest dated cases.
I have a 30mm RAKED disrupter case made by MF in 1986 too . (Shortened DEFA).
Information on Australian production is non-existing it seems. I wish I knew more.
I also have found unpainted projectiles from the MF factory. The above example seems it has the paint removed as EOD says otherwise a factory unfinished , unpainted example. Ron.
