What brought this on is that I've come across some ROC cloth insignia with some WW1 medals (all for disposal), and recalled there was a bunker at Shilbottle somewhere. The hatches into that tank look the same as bunker hatches elsewhere online

but I suppose a hatch is a hatch.
Is the bunker intact or vandalised do you know?
I get the cap badge from time to time. The long service medal much rarer beast at £200 up.
