Hi. I have a nice ww2 japanese 155mm case in vgc condition,i had the marks identified years ago and was told that it was for a 155mm mountain gun,and was made by the Osaka Arsenal(i think!!)the marks being crossed cannons.I would like to know if anyone has any info on the case,ie correct size and gun type,but especially on projectile types.A pic of one would be great,as i dont think these are very common.ANY info appreciated,Many thanks in advance.T.
