Craig Totney was also a follower of Blood & Honour, a neo-Nazi music promotion network and political group founded in 1987.
It is banned in some countries but not the UK and is composed of white nationalists with links to Combat 18.
The group organizes white power concerts by Rock Against Communism bands and distributes a magazine of the same name.
Totney, aged 40, was stopped on arrival at Birmingham International Airport from Germany by officials who seized his phone for analysis on May 22 last year, Wolverhampton Crown Court heard.
This led to a raid on his home in Bournebrook Crescent, Halesowen, by the West Midlands Counter Terrorism Unit on November 13, said Miss Sophie Murray, prosecuting.
The swoop recovered a CS gas spray and stun gun together with fireworks, a baton, stab vest, machete, three knuckledusters and a Samurai sword.
These were all capable of being used in violent incidents but there was no evidence that they had been, the court was told.
National Front stickers, a Nazi arm band and right wing magazines were also recovered.
There were pictures of Hitler and right wing memorabilia among the phone data that further revealed Totney had been communicating with 32-year-old Ruth Hollingsworth, a woman he knew socially but one who classed herself as a 'leftie.'
Among the subjects discussed was his offer of a Taser disguised as a torch, allegedly acquired via the internet from Lithuania.
She said she would not mind having one for her personal protection although she realised it was illegal.
Hollingsworth turned down the additional offer of a knuckleduster, it was said.
Police raided her home in Cecil Road, Selly Park, Birmingham, on the same day as Totney's house was searched and found the weapon still in its box with enough power to issue several charges.
The prosecution accepted she had been persuaded to take it by her co-accused who had tested a Taser on himself, the court heard.
Judge Nicholas Webb said Totney had been a highly regarded employee of the NEC but the evidence indicated he knew what he was doing with the weapons was illegal and a long sentence was required to deter others.
Totney, of previous good character, admitted possession of a CS gas spray and stun gun and transferring a stun gun to Hollingswood, who admitted possession of the weapon.
She received a two-year jail term suspended for two years with 150 hours unpaid work.
