Thanks for the info Martin. I was able to find this only from e-bay Germany – the price seems very reasonable indeed, but unfortunately it seems very difficult to order from there to Finland (the pages are in Germany and it would require some kind of identity verification by post office or something). The picture of the belt for Beogram 1000 there

Hello, I have a Beogram 1000 type 5203-5. I would need the belt measurements (length and thickness) for it. It has a round belt. Any help would be appreciated. Regards, Ville
