A few members have posted referencing a resource known as the "Pfalz Factory Film." Apparently this was a WWI documentary movie taken at the Pfalz factory documenting the steps in construction of an aircraft. Those who have seen it seem to believe it is a valuable resource for WW1 construction methods and a particularly valuable resource for anyone building a Pfalz replica. The subjective run time of the movie appears to be about 1 hour and 15 minutes, but I have heard enough variation in run time to wonder if perhaps there is more that one version of the film circulating.
Does anyone know where to obtain this film? I have heard stories of a company in Germany that leases copies of the film at an exhorbitant price with a restrictive agreement to prevent duplication.

This type of resource needs to be widely available. Any copyright should have expired by now.
I am posting this request for information under "Aircraft" in the hope that it will obtain better visibility on the Forum. Collectively we need to figure out how to make this resource easily available.
