75mm AP-P-T Shot US?

[tigbrand]

As the band has gone i can't really id the exact designation of this practice shot, I thought it was an M72 until i looked in daylight, totally different, no boat tail and two crimp cannelures.
It looks like M55 is stencilled on it? Could it be Belgian?
It weighs 12lb7oz or 5.65 kilos.

Hi,
The general shape makes me think to a 76mm rather than a 75mm.
M55 BG could be a Belgian marking as you said.

Possible US AP Shot M79 76mm and 3 inch.

Is it threaded for a base fuze? Hole for a tracer element?
