A motorcycle repair mechanic who operated a deadly firearms conversion factory behind the facade of his Lake District garage has been sentenced to 22 years and three months in prison. Dudley Brennan, 31, used his Kendal-based business as a cover to supply converted weapons to criminal gangs across the country, while simultaneously plotting to establish a large-scale crystal meth laboratory targeting vulnerable addicts.
The Criminal Enterprise Uncovered
Brennan's secret criminal empire collapsed dramatically in March 2024 when armed officers from the National Crime Agency (NCA) surrounded his industrial estate headquarters in Cumbria. With an Army bomb disposal team on standby and a security cordon in place, police ordered Brennan outside at gunpoint before conducting thorough searches of his premises.
Firearms Conversion Factory
Investigators discovered a sophisticated firearms conversion operation within the garage, where a Makarov-style semi-automatic pistol was actively being modified to fire lethal 9mm ammunition. The search revealed additional bullets, a silencer, and evidence that Brennan had already converted at least two submachine guns along with numerous other pistols.
The mechanic worked closely with Liverpool criminal Peter Weston, 40, who coordinated their organised crime group as the primary sales broker. Their business model involved converting top-venting blank firearms for criminal gangs to use in violent feuds and territorial disputes, anticipating significant profits from this deadly trade.
The Breaking Bad Meth Laboratory Plot
Simultaneously, Brennan and Weston were developing ambitious plans to mass-produce crystal methamphetamine. A search of Brennan's Kendal home uncovered a small production laboratory in his kitchen, with digital communications revealing detailed discussions about scaling up operations.
Brennan believed they could produce approximately 100 litres of the Class A drug within a 12-hour period using custom-built equipment housed in a mobile catering trailer. In messages referencing the popular Netflix series, Weston wrote "Ha, Breaking Bad" after Brennan sent him an advertisement for a 1989 Chevrolet GMC Allegro vehicle they planned to use for their operation.
Previous Criminal History
Despite presenting himself publicly as a skilled mechanic from a family of engineers, Brennan concealed his criminal background. He had accumulated convictions for firearm and ammunition possession during a decade spent living in Australia before returning to establish his garage business in 2021 with his mother as co-director.
Wider Criminal Network Sentenced
The investigation revealed Brennan received deliveries of Turkish-made Ekol top-venting blank firearms at his Fell View Trading Park garage, arranged through meetings coordinated by Weston with co-conspirators Daniel Fitzgerald, 32, and Ryan Pilling, 29. Investigators established the group had purchased and converted 17 firearms, with 12 successfully recovered by authorities.
At Bolton Crown Court, Weston received a sentence of 26 years and nine months for his central role in the conspiracy. Pilling was jailed for 13 years and seven months, while Fitzgerald received an eight-year sentence. Joshua Ee, 27, who handled weapons for the group, was sentenced to 13 years and six months imprisonment.
National Firearms Amnesty Context
The case emerges against the backdrop of national efforts to combat convertible firearms. In February 2023, nearly 3,000 Turkish-made top-venting blank firearms were surrendered during an NCA and National Police Chiefs' Council amnesty. Testing confirmed these weapons could be readily converted using common DIY tools without specialist skills, making them illegal under the Firearms Act 1982, with possession carrying potential 10-year prison sentences.
NCA branch commander Cat McHugh stated after sentencing: "Brennan and the group were only interested in making money and didn't care at all about the harm these firearms could do in our communities. They were a real danger to the public. Tackling the criminal use of firearms is an NCA priority and we will continue doing everything in our power to achieve that."
