Australian 3.5" Rockets.

I show two 3.5" Rockets that were loaded in Australia but the heads were made by British Tube Mills (BTM).
It seems odd that empty rocket heads were sent to be filled and fitted with Australian made motors.

Thanks TimG.
That makes sense that BTM ( Aust ) made these rocket heads. I did not know of the Kilburn factory.

What about the 40mm Bofors chromed drill N2 9-58 with red flutes. Australian or British? I assumed it was British made until now.
