The 1/8th scale castings of the 80hp were done by Pacific Model Design (PMD), same company that did teh castings for teh Monitor that I made a couple of years ago. Unfortunately they went out of business and the patterns went somewhere but at the moment no new castings have appeared.
You may get lucky asking in teh Scale model section on Smokstak forum and find someone willing to share some plans. I have a feeling I have seen one done without casting, will have a look later.
