GLOC'N STEAL ' Pistol tycoon's ex-wife claims he's robbed family of share in PS1.8bn firm ..after marrying former nurse 50 YEARS years younger.
A BILLIONAIRE gun maker is at war with his family after the 83-year-old fell for his glamorous young nurse.
Gaston Glock, a former radiator engineer, made his colossal fortune after designing a pistol that saw off all rivals to become Nato standard issue in the early 80s.
The Glock handgun's phenomenal success spread to 45 countries by 1992, and 250,000 were sold in the US alone that year.
With the business worth PS1.8billion Gaston divorced his wife of 49 years in 2011 and married a woman 51 years his junior - Kathrin Tschikof, 32.
He also fired his ex Helga, 71, and their three children from their jobs and cancelled their stake in the company.
Now Helga has started a civil case, claiming her and the children's interest in the firm was improperly shifted by her ex-husband's advisers after he had a stroke in 2008.
Helga says Gaston's bride Kathrin, who was one of his nurses at the time, "seemingly developed a close personal relationship" with her patient.
The suit also claims Helga "learned that Gaston Glock obviously had extramarital relationships for years".
Fool She says she was denied access to her husband's hospital room and later locked out of the family mansion without her personal belongings. She fought for a year to get them back.
Glock's youngest son Robert, who gave up his ambition to become a lawyer so he could help expand the family business, said: "I don't know him. I don't know my father any more. The family was always the most important thing for him.
"I don't understand why he doesn't remember how long he was together with his wife, my mother. He was absolutely fine until he had his stroke. After that we lost him."
He said his father's relationship with Kathrin hit them hard, especially when he married her in July 2011.
Robert said: "My mother only found out about the marriage of our father through the media. We thought it was an April Fool joke except it wasn't April."
His dad even took verbal potshots at rich old men who run around with young beauties.
Robert said: "I can remember how my father said to me, 'Look at all the idiots with their pretty little dolls.' "My mother is really suffering. He always used to ring her twice a day, even when he had this girlfriend. He always gave her presents." Kathrin moved into the SOLD: Test Glocks' luxurious mansion on the shores of the Worthersee, a lake in southern Austria.
She has unlimited access to two private jets and a helicopter.
Her husband's wealth allows her to indulge in a passion for riding and she was made chief of Glock Horse Performance Centre, one of the country's best equestrian establishments.
Meanwhile Helga is battling to get back her 15 per cent share in the Glock company which Gaston, who had the other 85, reduced to zero in 2011. At stake are future earnings that make lottery wins look like pocket money.
The now legendary pistol, his first attempt at producing a weapon, is used by two out of three of US police departments. It is the latest weapon of choice for the British Army, which has ordered 25,000 as part of a PS9million contract to equip troops in Afghanistan.
Helga's case includes a trust she and Gaston created in 1999 to ensure continuing family ownership. Documents said each spouse was contributing "considerable assets".
In 2011 this was amended to cut out any corporate role for Helga or Robert and his brother Gaston Jnr and sister Brigitte.
Robert said: "At the end of the day he had a stroke and it was clear then that his girlfriend was playing a very important role. He came under another influence then.
"When my brother Gaston Jnr went to visit my father in the summer he told him that his bodyguards would need to check him.
Ruthless "I've told him I don't understand him any more and I was worried about him.
"He just brushed me off and said everything is OK. It is extremely painful."
He added they were asked to leave the business "because of differences with my father". And he denied claims each of the three children were given PS22million to walk away and renounce any future stake.
Robert said: "I wanted to be a lawyer but I wasn't allowed to do that. He wanted us to dedicate our lives to the company because he wanted us to take it over one day." But today Brigitte has a pet shop in Vienna and Gaston Jnr a clothing business in the US. Robert, who runs restaurants in Austria, said: "I retain a sense of injustice."
His father recovered from head injuries inflicted by a rubber mallet in the hands of a hitman in July 1999.
The attack was ordered by one of Glock's most trusted aides - his financial adviser Charles Ewert, who was afraid his fiddles would be found out.
Amazingly the tough 70-year-old got up and knocked his attacker out.
Ewert was jailed for 20 years and his hired hand Jacques Pecheur for 17.
Since then Glock has been ruthless in ordering investigations to root out anyone suspected of stealing.
Last year he was accused of pointing a gun at the head of a photographer who bothered him. He fired a jet of water before saying: "I bet you're glad that this is not a real gun."
His publicity chief told reporters: "Gaston Glock won't comment on ongoing proceedings in Austria."
firstname.lastname@example.org FBI toHollywood GASTON Glock was the engineer boss of a radiator firm in Austria when he entered a competition to design a pistol for the army.
He knew little of weapons but he was an expert in plastics. A team he put together in 1982 produced their Safe Action pistol, which had a frame of Glock's own super tough and durable polymer.
The "plastic pistol" spread to the world's police and security forces, including the FBI. Soon it was spotted in Hollywood films such as Die Hard 2. It has also been used in a number of civilain shooting sprees, including the massacre of 23 people in Killeen, Texas, in 1991 and the 2011 Arizona shootings which killed six and left congresswoman Gabrielle Giffords and 13 others injured.
