Szeged!  There's a spice factory there called Pride of Szeged!  They make really superior hot and smoked Paprikas, and a Fish Rub and Chicken Rub blend that I use all the time.  You may be able to find them at your local megamart!  Make a big pan of Paprikash (chicken and dumplings with lots of paprika) and play your citera while it cooks.

Seems that my maker is no more as this translation of a press release explains

The Szeged Instrument Factory was established with 50-60 employees in 1953 as a council company with a mixed profile: in addition to the instruments, furniture manufacturing, upholstery and decorations were also operated. It later concentrated on instruments and due to a downturn it was closed in 2004 after it peaked production at 9400 instruments in 2001

This chart gives you a fair idea of what the tunings should be on a Citera..............by the way, a great find!

The pins appear to be standard zither wrest/tuning pins that will take a  5mm square wrench or socket
The original key does not give the fine control that a long handle wrench does so I will repurpose one of my 'old' tools

My folk Citera arrived today 
Made April Fools Day 1981 and never played
Here is a link to Flickr pictures ....

The pictures show the makers label various details and the original spec sheet.
Any help translating the spec sheet and the suggested tunings will be appreciated greatly!
I found the makers address on Google street view but it is a modern block of flats
I have so far not found any other info on the maker
I will set about getting it into a playable condition over the weekend
So wish me good fortune!
 

The pins appear to have a square head -- should not be hard to find a clock-key to match.

I believe that the 'Rosebud' carvings may be the best method of identifying the maker
Any help will be gratefully received
Cheers Dave

It would be nice to have a real closeup of those tuning pegs, but I'm betting that they are autoharp pins, for which you can buy a clock-key as a tuning key.  When you get it, measure at the top of the pins, across the flats, and I can help you find an appropriate clock-key.  They usually run a whopping $4-$6.

Thanks guys I also posted on ED and have been following many internet threads chasing info.
I did not set out to buy this but the lady advertised it as 'Musical Instruments' in amongst the 1000s of acoustic guitars and never amended her add even though I informed her what it was.
I have always been fascinated by the fretted zithers, auto harps etc but never thought to own one unless I made my own.
I got this by default with a single bid and am very happy.
It may well cost me as much again for a decent tuning key.
I will post detailed pictures when the package arrives meanwhile I am hunting for any possible info on a maker

That's a lovely instrument Dave!

Don't forget you can use Google to translate Hungarian webpages to English.  It won't be a perfect translation bu tenables you to understand most of the info.

You may benefit greatly from watching Youtube videos of Hungarian citera players in action.  It'll show how they utilize all those strings when they strum.  Remember also that Youtube has a setting where you can slow the video down to half speed while staying in the same pitch.  That way you can watch their hands better.

I transferred this thread into our 'other instruments' forum, btw.

At is happens, we're having a great Citera discussion on ED, here:

Search the 'Net on "Hungarian citera" there is a wealth of info.

 was browsing Eb** and came across an interesting chromatic dulcimer otherwise known as a Hungarian citera zitherI just won the auction and now need to collect info about citera s that I can understand[Hungarian is not a language that is easily translated]Seems to be a 'C' tuned instrument but what do I do with all those other strings?Seems to be set up like a short scale dulcimer with the black notes on the second fingerboard and drones
