A short steel cone on the muzzle.
Threads tightened under a field wrench.
A smooth taper checked by inspection gauges.
One grit scratch left a visible scoring line.
Clearance paperwork followed the part, not the crew.
A test round went out, then a misfire.
The report was sealed the same night.
By 1942–1943, Britain needed quick answers.
German armor outpaced older anti-tank guns.
The QF 2-pounder still filled many turrets.
Full rearmament meant new mounts and delays.
Factories were overloaded with higher-priority programs.
Tungsten was scarce and tightly audited.
So planners favored bolt-on upgrades over replacements.
That pressure produced the Littlejohn adaptor.
It turned the 2-pounder into a squeeze-bore system.
Special ammunition collapsed from 40mm to 30mm at exit.
Velocity rose, improving short-range penetration on paper.
In practice, the advantage came with friction and wear.
Scoring, strict ammo segregation, and field handling risks followed.
Limited supply and inspection realities kept it a niche tool.
