37 x 57R M 15 HE projectile

[ron3350]

I have an empty 37 x 57R HE projectile. (not the bounding type).
The pointed steel fuze at the top unscrews but I cannot easily move the section above the body.
Is it a normal right-hand thread like the fuze top? I have not tried left-hand thread yet so hope somebody has one to check if right-hand thread.
Shell has no powder or explosive inside.

Same as the top part. You need to turn it counterclockwise to unscrew.
