Hello, my friends!!
Congretulate me - i've bought simson s51 in Moscow!!! For about 200 with one more engine and wheel.
It os in normal condition, in addition i don't have headlight, flanke and some small parts =( but Though i'm happy like a child.
If you are interested i can upload photos.

Here they are

It is 85 year of building and s51 without any letters.
How can i understand that it has 12v ignition?
On rotor is written 830-...
I need many spareparts, so can i buy them in akf-shop.de?
They say that they make shipping to russia, but when i asked for more details nobody answered... I need to shure that i send money to the right company.
