| Notes | A nicely proportioned model of a mill engine which Stuart
produced in large quantities as fully-machined kits for assembly with hand
tools only. Consequently, most S50s run pretty well - be aware though that
raw castings were supplied and some engines were amateur machined.
Good examples will run slowly with their long stroke configuration and are rather pleasing to watch. |
