WW2 Finnish 20x113 inert anti-tank rifle cartridge

WW2 era Finnish 20x113 cartridge for the Lahti L34 “boat gun”. More accurately used as a shipboard costal defence weapon, only a small handful of rifles ever entered service. 

Projectile is solid steel with a tracer in the bottom. It is either a mild steel TP-T round or an AP-T, unsure of which. Cartridge is unfired but had the projectile pulled which left 2 cracks in the case neck while the primer is oiled. Inside the case is the original silk powder bag as well. Headstamp reads “T 40”.
