Got some info from a fellow collector regarding a case
06673001 means factory 066 = Liab Lindesbergs Industri AB. 1973 Lot 1.
But I am a bit hesitant about the projectile, driveband suggest fired but looks like a different metal in the base
Projectile is marked R-HS, length from band to top 21.5mm. Projectile top part diameter 17.5mm
