Police seized firearms and CS gas canisters when they searched the home of a farmer’s son after they were called to a domestic dispute, a jury was told.

Richard Bamford, 38, is on trial at Bradford Crown Court accused of illegal possession of a walking stick gun and the component parts of a sawn-off shotgun found by officers at Model Farm, Toftshaw Lane, near East Bierley, Bradford.

Bamford, now of Brookfield View, Cleckheaton, denies possession of a disguised firearm, possession of a prohibited firearm and two charges of possession of CS gas canisters as prohibited weapons.

His case is that the two old guns are legally held antique weapons.

Prosecutor Simon Haring said yesterday that the police were called to an “ongoing domestic incident” between Bamford and his father, Allan Bamford, at Model Farm on April 10 last year.

Bamford had several legally-held shotguns kept in a locked gun cabinet.

His home, at the Gatehouse on the farm, was searched, along with his former bedroom in the main building.

Mr Haring said the police found a collection of military items, including decommissioned guns, bombs and grenades. There was a wooden crossbow, assorted ammunition and a rocket launcher.

“Police also came across four items that the prosecution say are not legal and they are the subject of the charges on this indictment,” Mr Haring said.

The walking stick firearm, found at the Gatehouse, had been test-fired four times by an expert. Manufactured between 1893 and 1924, it was still a viable shotgun that would fire standard ammunition available today, the Crown alleges.

The shortened side-by-side hammer shotgun, found in a storeroom in the main house, had “numerous small components” missing and only one viable barrel, the jury was told.

It was made between 1870 and 1904 and designed to fire gunpowder.

The prosecution’s case is that it is “the major component” of a gun and that both weapons would need a letter of authority from the Secretary of State to be legally held.

Bamford’s barrister, Simon Batiste, said it was legal to possess antique firearms that were “a curiosity or ornament.”

“The jury will have to decide if the two items are antiques or not,” he said.

Bamford told the police the shotgun and the gas canisters came from a flat his father used to rent out. The walking stick gun had belonged to his father and he took it back to his home.

The trial continues.
