j&h gerkinet herstal
Hi,
I have a really old rearwheel from j&h gerkinet herstal (firm J. H. Gerkinet from Herstal). It looks like an old wheel from an old puch or other bike. Now i want it to use it for my old cargo bike. The wheel is 28 inch, 5 cm wide and i'm looking for a tire. This is difficult. Is it a 50-609 wheel or another one? Do you guys have any idea? Can you help me?
Or are you interested? It is in really good condition.
Best,
Joost Bout

Hello
I have found this 350 model in south France (where I live) and I have some more documents.
What do you want to know (except philosophic answers!)?
