I show Australian M103 TP cartridges, projectiles and a container.
Australian TP is a lighter blue than what seems to be an American projectile overstamped M55(AUST).
It is stamped above the drive-band: WM-92L 001-001 M55A3B1. Who is WM ?
It seems we used USA projectiles in Australian cases at ADI in 1993?
I remember finding these projectiles with pull marks but not marked as Australian. Maybe used in trials? Comments welcome.
