I've been trying to find out what instrument the "Third Man" was played on for many years. I've bought zithers, NO CHANCE. I've bought Autoharps, Still got one and it's great but it's NOT Anton Karas. What you need is a "Koncert Zither" I finally got one from E.Bay Austria. You can access different country's E.Bays quite easily. (bottom of the screen) I had to do the whole transaction in German (GREAT learning curve) with the aid of a translating site but it was SERIOUS fun! So, if you want to 1st find out what it's played on, and 2nd learn how to play it. search worldwide on E.Bay for a Koncert Zither (Concert Zither) and then go on to YouTube. Find Anton Karas, load them all. It's a bit like searchimg for the Holy Grail, but believe me it's worth it! You'll be looking at thick end of £500.00 but it's worth every penny and if you get one you'll have the second one that I know about. I've trawled the internet for nearly three years to find a good one. It's not the most difficult thing to play basic tunes on but it's like the SIRENS, it'll take you in and NOT let go. GOOD LUCK. BUY A GOOD ONE, don't waste money. Like any other musical instruments there are poor and average quality. BUY THE BEST! You''ll take it to the grave with you!
Bon chance,
