An AK-47 and an Uzi machine gun were among weapons found by police searching a cottage in Suffolk, it has emerged.
Police said 50 officers had been involved in investigating the «significant» find in Potash Lane, Wyverstone, since 27 March.
A search of the area will continue for at least a week. Wyverstone Parish Council chairman James Arnold has been charged with firearms offences.
Mr Arnold, 49, of Potash Lane, is due at Ipswich Crown Court on 1 May.
He is accused of being in possession of a self-loading rifle gun, a bolt-action shotgun, a Uzi machine gun and an AK-47 assault rifle.
Police said they were initially called to the house over an allegation of assault, and then carried out a search warrant.
A 50-year-old prison officer has been released on bail after being arrested over drugs offences.

A member of a gang in Niger says Boko Haram Islamist militants from Nigeria regularly come across the border, looking for recruits.
«We can’t contact them, they come to us,» says the young man, who looks like he is barely out of his teens.
Five members of this gang in Diffa, near the border, have joined the group; two have since been killed on operations, he says.
In total there are about a dozen gang members in a tiny, dark room, built with local mud-bricks.
There are a couple of homemade stools and weights for them to exercise just outside the door.
When I ask if they agree with Boko Haram’s reason for fighting, they answer in unison: «No. We only do it for the money.»
They had agreed to meet us earlier on a street corner in Diffa.
Journalist Wilf Mbanga was once a close friend of Zimbabwean leader, Robert Mugabe.
Mr Mugabe rose to prominence as the leader of ZANU, one of the armed movements fighting a guerrilla war against white minority rule in Rhodesia.
In 1980, Robert Mugabe won historic elections which were part of a peace deal to end the conflict. Rhodesia was renamed Zimbabwe. He was initially praised for reaching out to the white community and including political rivals in government.
But in the early 1980s, he expelled his rivals from office and unleashed the security forces against opponents. In Matabeleland and Midland provinces, the strongholds of the opposition, thousands of civilians were killed or imprisoned.
Russian officials say a water shortage in Crimea is threatening to become acute as Ukraine has reduced the supply via a key canal.
Ukraine does not recognise the new authorities in Crimea who are backed by Moscow. Russia made the peninsula part of its territory last month.
Crimea’s harvest of grapes, rice, maize and soya will be ruined if it does not get more water soon, officials say.
Russia says the Crimea-Ukraine border is now officially a state border.
The Russian government plans to establish permanent checkpoints there, as well as new rules for entering or leaving Crimea, Ria Novosti news agency reports.
