37mm Finland Projectile Copper Band

Can anyone ID this projectile and show me what the copper driving Band looks like, a drawing would be great joe gatz

Projectile probably had a driving band like in the standard Swedish and Polish 37 mm Bofors shells.
[I’m not 100% sure what kind of model it is.]

DB for AP model 1936 (in PL), based on original Bofors drawing:
