My father has a partially built model stationary engine and boiler that he started building with a friend probably more than a decade ago. He is getting older now and his vision is poor so he is unable to complete it. It has been passed amongst some of his friends who have each worked on it a bit, but unfortunately as they are getting older, either their vision has started to go, or they have passed away.
He is based near Retford in North Notts and is hoping that someone local would be interested in completing it. I don't know much about it, but if anyone is local and interested please drop me an personal message and I can put you in touch with him directly.
Regards, Jonathan
