.303 Brit "AI 53 A"

What's the meaning of "A" in this Dutch .303 Brit made by Artillerie Inrichtingen?

Brass supplier???

I saw similar headstamps at Municion.org where it was said to be "A" lot (1st lot of the year?), but one headstamp was "AG" where "G" was said to be a tracer. Here there is no specialty assigned. Am I to assume it is just a ball round?

 

[Dutch]

The British rounds use Mark I,II and so on
The Dutch A,B,C.
Means this is the first type case.

I can Show it by the 7,61x51. Case type "C" and "D"

The marking on the tracer is not AG but GA. :tinysmile_hmm_t:
The round must have a red tip.
