How inconsiderate. It was there this morning. Anyway: "An ex-Royal Navy gunner has discovered remnants of an extremely rare gun from World War One in a yard full of military paraphernalia on Dartmoor. Ian Chatterton, a member of staff at Trinity Marine, made the discovery when tidying a 'quiet corner of the yard'."
That's all I know. I bow to your superior . . . etc.

That's interesting - the projectiles were numbered and had to be fired in order since the bore gradually increased as the gun wore, I had read the propellant loads
were increased as well but it could be that there were graduated cartridge cases as well.
Thinking about it the fate of the Paris guns may be an inference based on the Allied Control Commission failing to find any sign of the Paris guns after the war.
The WW2 21cm K12E also used numbered (splined) shells. Possibly therefore numbered cartridges also. It certainly used cartridges rather than bag charges. One was discovered by British forces in Holland, destroyed by the retreating Germans as it could not be recovered across the Scheldt. the second gun had earlier returned to Germany for repair.
Assuming this to be correct, it would seem more likely that the cartridge discovered is from that wrecked 21 cm K12. Of course, knowing the neck calibre would help.
But the number could be entirely spurious. A later display or inventory number, perhaps.
