Okrasa 78.4 crank worth €??

[Type1/DVK]

I've scored this 78.4 Okrasa crank today and it's in a good condition on the journals, grinded to 0.25 on the mains



I've searched all topics here and on google, some prices vary from $200 to $600

These cranks arent laying around everywhere, so best to hang on to it or to sell it? and what could it be worth? I've got no intentions (yet  ) of building a 2165 or somewhat else..

Thanks,

Martin!

Yes they were a good crank and were copied with their design
firstly with the bug pack and in recent years, nearly all the chinese cranks.

Seems supect that the mains-only are ground,
and it looks to me like the rod journals have been ground down to chevy?
The ones I have seen, all 78.4s came as VW journal, and the 84s were Porsche.
This is not to say that there were not others,
only that yours may have been f?*ked with.

Yes get it crack tested before getting too excited.

Thanks for the reply's! I've got some more images of it. Doesn't 'seem to be' a knock-off to me

Journals are std vw and mains are ground 0.25 (they could use another 0.25 though..) and/or good mains polish

When i have a purpose for it, i'll send it to Udo for inspection and so forth.









If you can tell if it is a knock-off or the real deal, that would be great, thanks!

If it is ok you made a very good deal

Besides the cast-in okrasa logo, the above star with (I suspect) Alfing writing below it is pretty conclusive its original.
I also suspect its cross-drilled like original, which new chinese cranks don;t have afaik.
These were truely forged cranks, made by a upper end quality german small-batch specialist crank maker.
It would make for an awesome turbo engine crank
