Thanks to Olaf Greves excellent site on Japanese ammunition, I have confirmed that the Japanese 25 m/m x 163 dummy round that I have had in my collection for some time, is exactly that. My round has all the attributes that Olaf describes on his site with regards to one particular type of dummy round.
The one piece case and projectile have been profile machined from solid steel and the interior has been machined hollow, the fuse is a solid brass turned unit. The threaded removeable base section in my example is locked in place by a very small grub screw. Apparently the round should be painted black but it was in bare steel when I acquired it. The only markings present appear to be acceptance stamps or something similar due to their small size.The only downside to all this is the fact that someone in its past has seen fit to drill and tap the base...no doubt at some time it has spent some time doing desk duty!
