Headstamp is DAC ( Dominion Arsenal) 43 20mm
Fuze is LOT -47-ZZ415-59-42
with 253 IM /N0 ? underneath - bit hard to read
Projectile MK3 24 LMLST ? 27
Projectile has a solid base so I would think not a tracer. It 's not straight, being a bit wider at the top.
This is a new to me, I normally collect German aircraft ammo!
Thanks for your help
Roger
