Hi Bryan,
Progress on the restoration is very slow as my friend has many projects going at once. Last time I asked him, he had finally reproduced the needed parts for the engine and had assembled it. Beyond that, probably not much else has been done.
Any information you can share would be greatly appreciated! Have any photos?
As a side note, he was visited a few months ago by the guys from the show "American Pickers" on The History Channel.
Here's a link to an interview with him after the filming:
