25mm round?

[Jjs92186]

Hello all, I have this shell and projectile I know that it is 25mm. But does anyone know what kind of round? Thanks Joe

From a quick search I think it’s a High explosive incendiary round for the Type 96 25 mm AT/AA Gun

Looks really nice by the way

Thank you I was searching but couldnt find any with the green paint.

I'm skeptical green paint is period & not a post war repainted

The navy did have green-coded shells, though I wouldn't want to go through the trouble of reading their thick manual to find out what purpose it signified.

Here is the colour schemes and what they mean as taken from a US document

25-mm – Automatic antiaircraft weapon: This ammunition follows the large-caliber system in part. Green tipping to indicate the presence of explosive filling was followed in H.E. and H.E.-tracer projectiles of earlier manufacture, but apparently has been abando-ned in more recent lots.

Maroon (with or without green tip): High explosive.

Red (with or without green tip): H.E., tracer. Later lots only are self-destroying.

Orange (with or without green tip): H.E., tracer. Identical to red non-S.D. rounds.

Orange (with red paint around the case primer): H.E., tracer. Construction of tracer dif-fers from above.

Green: H.E.I. (W.P.).

White (with black under coat): A.P.-T. Projectiles sometimes appears bluish-white, white-tipped, or black due to loss of white paint.

/ for this shell being a repaint i could not say, i have never encountered Japanese ammunition before.

Here is a diagram from the same manual of the original posters shell
