1913 Harley Davidson twin engine wanted

The above has to be a 1911,1912 or 1913 HD twin ,the engine below went in a bike like this.

A fellow i know recently discovered this 1913 HD twin engine. This technology is before a recirculating oil pump was introduced, note also no valve covers, they surface in 1914 models.
If you have one of these early engines, email me. i would like to build a racer, just go to the profile page , look for contact info...
