A late reply but I had no computer for 9 weeks so busy catching up on forum items.
Yes this is a TP 2102 DEFA that is only undercoated and base marked in black.
The projectile then gets filled with a pinkish inert filler, blue painted and stencilled in white print.
The projectile date can be a earlier year to the filled date.
The dummy fuzes are nearly impossible to unscrew without severe damage. Too tight.
I have mis-matched the copper banded TP date of case and projectile to show the best case print with a TP projectile that shows the red undercoat where the paint has flaked off.
I believe the FR means French ammunition made under manufacturing licence.
Australian made TP 2102 and HEI-AG 6522? for air-to-ground use and had a primer extension tube to transfer the flame to the centre of the propellant load. AG tended to shift the powder forward when the jet dived and the emphasis was on fragmentation rather than blast effect.
There is next to no info on Australian ammo other than what collectors have found.
I have two cases for the AG ammunition. One looks like an experimental lot number.
The first date I have found is 30-550-DEFA 6 MF 70 FR. Highest lot is 22 MF 70.
Later years seldom had lot numbers greater than 12. Always looking for missing dates.
I note TP 2102 with copper bands and also steel de-coppering rounds.
See the container held 28 copper and 2 steel belted rounds.
I have a HE empty fuze and it fits the TP projectiles. I have never seen a HEI Australian projectile or Dummy rounds. It is hard enough to find a nice fired case with load data on the side.
I collect all lot numbers and H/S styles and hope to finish an article for ACCA Journal some day.
