Does anyone have any info on actors Jan & Hans van Noord

I am looking for information on Jan & Hans who both appeared in The Girl From U.N.C.L.E , Season 1 Episode 19 - ' The Drublegratz Affair' that aired January 31st, 1967.
I was recently talking to a friend, Leslie Amos, who remembers them when they lived on Landing Road in Sackville,NB Canada in the 1950's, early 1960's. Leslie remembers when Hans & Jan stopped at his parents house to see if his brother Reg Amos wanted to go to Hollywood to become an actor with them but neither Leslie nor Reg has heard of them since. I would appreciate it if anyone could pass on any information about either or both of them to me. Thank you very much, Dave Bailie ( [email protected] )
