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

I am locking this thread. Most of what can be said has been written here (above).


We have a clear case of design copyright issues. The engine as shown in the drawings Jin has published here clearly incorporate the design changes made by George.


The Holt 75 Caterpillar engine was offered for many years as a casting kit from Coles Power Models. George Britnell spent many hours (400-500)
perfecting design changes that would allow the construction from bar stock.


My intent from this point will be to facilitate an amicable end to any disputes here.
