it is in German but you will figure out what you need to know.

I think I figured it out:
both the engine number and engine serial number match this listing

No idea. But looking at other motors, sounds about right. Good luck with that.
Stay in touch, perhaps join the local PCA Niagara Region and come out to a few events. We have a DE in October at Watkins Glen. Car or no car, come out and see what goes on at the track. :D it's like giving candy to a baby...you never get enough.
