I'm sure many of you remember Joe, who passed away in 2015. . I was able to rescue his model engine castings and patterns after his death. For the past year I've been completing four of his partially built Wall motor and recently started a fifth.. It is Joe's version of the 1930'd Wall Mariner Duplex 2 cycle, which Joe redesigned as a 2 cylinder overhead cam 4 cycle. . In the assortment of castings I found enough left to comprise 6 casting sets. . Here is my partially made project as I work through Joe's notes and plans. I did not find where Joe actually sold this kit although he did display one for the BAM's magazine. One of his friends in San Francisco also had one he built. . any others out there?
