Every radio I ever heard in Poland carried voices speaking in Polish. If you are getting one of those, I sure hope you can understand Polish!
Seriously, there is a lot of interesting tube gear in the former East-bloc countries. They continued making what we would consider old-fashioned gear long after the West moved on to newer designs, so your new acquisition might not be as old as it looks. Build quality varies, and sometimes disappoints a little. Still interesting stuff, though!
