Many moons ago I took a wee daytrip to Landan town (from Glasgow)& bought a deactivated Bren from a wee shop in Angel Islington, as you can imagine the box it was packaged in was mahoosive. Popped on the Tube to go catch my train home and when I got to Euston station I thought... hmm, the IRA are still a thing, I better leave this with the transport police until I catch my train home. Long story long, they weren't interested, "take it to left luggage if you want mate".
I'm still shocked 30 years later.
p.s. cool build.
