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

This is the second engine i have purchased this week that you could call real vintage, an Ernest Plank vertical engine ...im not sure of the model or date.
It runs very well but being a small engine it had to work hard to run the water mill in the video but it did manage to run it for a bit
Any advice on the date and model would be useful ...heres a video to enjoy...Steve
