Hello,
Ok, it's a 17Pr round for practice but as far as I know proof shots may have a tracer (picture : example of WW2 German Proof 8.8cm).

I always understood that arrows on German ordnance (as shown on the illustration) indicated a practice projectile?
What purpose would a tracer serve in a proof projectile? Happy to be proven wrong, but I don't believe any British artillery proof projectiles had tracers.
