We were at Joe's model train shop in Feasterville, PA, today, and he had some boxed stock by Mehano, with the Philly address, and I became intrigued. From the Web, I see that it is a Slovenian HO train company, and it apparently manufacturers high-end merchandise for Europe and lower-end for the USA. I'm not sure whether there is still a Philly presence. Maybe someone can fill in the gaps.
