A former primary school head teacher has been struck off after a disciplinary hearing was told he was "deceitful" about his arsenal of guns.
Martin Wynn Davies was head teacher at Ysgol Deiniol in Marchwiel
Martin Wynn Davies, from Wrexham, was jailed for four years in 2006 for keeping 21 weapons, including revolvers and semi-automatic pistols and rifles.
He bought guns after tightening of laws following the Dunblane massacre.
The committee ruled his crimes were "fundamentally incompatible with him to continue as a registered teacher".
Mold Crown Court had heard how Davies was a gun enthusiast and was dismissed from his job at Ysgol Deiniol, Marchwiel, in August 2006 after admitting 23 firearms offences.
He kept a stash of weapons at his home and at his parents' home without their permission.
Some weapons were kept in a cardboard box in a garage, although it had been burgled previously.
He had admitted 14 gun and ammunition charges and asked for nine others to be taken into consideration.
The professional conduct committee hearing at the St David's Park Hotel in Ewloe, Flintshire, was told Davies had held the weapons for a number of years and had planned to deactivate them.
But Damian Phillips, presenting the case for the General Teaching Council for Wales, told the committee: "One must ask why have ammunition if the weapons were going to be deactivated?"
The school was also searched, but no weapons were found
Both the court hearing and the professional conduct committee heard there was no suggestion Davies had intended to use the weapons for criminal purposes.
Mr Phillips told the hearing that firearms laws were changed, banning handguns for "a very good reason" following massacres at Hungerford in 1987 and Dunblane in 1996.
Gunman Thomas Hamilton killed 16 children and their teacher at Dunblane Primary School in March 1996.
The hearing was told how the majority of Davies's guns were bought before the change in the law but he purchased some weapons for cash after the change.
"He was trying to cover his tracks," said Mr Phillips. "He was being deliberate and he was being deceitful.
"We're not talking about one or two guns, but a vast arsenal."
He said it was a "bitter irony" that Davies was a head teacher.
"Mr Davies stopped being a man of good character the moment he broke the law," he said.
"He was a headmaster, he was a role model, a leader of his colleagues and pupils.
"His behaviour is thoroughly incompatible with being a role model.
"He showed no consideration for the families of the victims of Dunblane."
Mr Phillips said Davies had acted in a "deliberate, calculated, sustained and selfish" manner.
In ruling that Davies be removed from the teacher register, the chairman of the committee, Gareth Jones said that the conduct of a teacher both in and outside work is subject to scrutiny.
"The committee is saddened that a registered teacher with such an illustrious career comes before us in such circumstances," he added.
The committee acknowledged Davies's convictions damaged the "reputation of the teaching profession and the public confidence in it".
Committee chairman Mr Jones said Davies had the right to appeal through the high court.
The terms of the prohibition order mean that Davies can seek permission to apply to be re-registered after three years.
