Rare firearms chosen for engineering and historical interest

Which rare firearm would each panelist most like to own?

Their choices include the H&K G11, an unmodified Pattern 1914 Enfield, a Vickers .600 Nitro Express rifle, the Czech ZGB 33, and heavy ZB-60 or 15 mm Besa weapons.

The choices include the caseless Heckler & Koch G11, valued for its unusual mechanism, and an original Pattern 1914 Enfield whose surviving military configuration is rarer than total production suggests. A Vickers-built .600 Nitro Express elephant rifle represents the improvised heavy counter-sniper weapons used during the First World War. The Czech ZGB 33 is important as the limited-production predecessor licensed into the Bren gun, while the ZB-60 and 15 mm Besa appeal as scarce heavy automatic weapons used in specialized roles. The exchange shows that rarity can arise from experimental engineering, later civilian conversion, or a short production run rather than age alone.
