I got a friend who wants to sell a totaly restored NSU 250 OSL dating of 1942 with a extra engine (bearing swa's stamps!?) AND a NSU 350 OSL dating from 1938 that needs to be restored.Both in one sale!
First one has Belgian papers, don't know about the second one.
I am just spreading the word, if intrested take a look at
Drifter forum holland ..::.. Onderwerp bekijken - Vraagje aan onze Duitse vrienden
You will find there a other link that redirects you the the pic's of the bike's.
Don't mind the language(it is Flemish!!) but German, English or French can be used on that forum.
