Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Thanks Bruce. You can see some "before" or "as found" photos in my 2018 posting on the Mamod forum here:

Make sure to read through all the replies and comments because some of the first ones were misleading. Then there's an Aug 2020 update. Next (final) update coming soon which I'll post on both sites.
