I have always assumed that these older cameras were so reliable that if they didn't look war torn that they must be in fully functional condition. And even if they were war torn, they could probably be restored. This has worked well for me as I have only been wrong a handful of times . . .
Is there a craigslist or local equivalent there? How about camera swap meets? Here in the US, I have found KEH.com to be a reliable place to buy these older marvels at great prices with a no questions asked warranty. I don't know how they handle overseas shipping.
