mystery aircraft

I was in Prague for a few days last week and on the Saturday whilst walking around the wonderful sights an aircraft wandered overhead that I could not identify.
It looked at sounded fairly old, it was a twin with twin tails, my immediate thought was twin pin as it was that size and souded similar, but then I saw the tails thus eliminating that type.It was a scorching hot day and difficult to see any markings , I only had a wide angle lens on the camera and it was at about 1000ft, so no photos either. I would guess something from the 50’s maybe later given that its an ex eastern bloc country which tends not to blaze a technology trail.
Not sure how well, if at all ,historic aviation is supported in the Czech Republic.
I unfortunately did not get to the modern history museum which apparently has some aircraft exhibits, although I don’t know what.
Great place for a short break though.
