Class member "Lady of the Lake" was exhibited at the Great London Exposition of 1862, apparently attracting a great deal of attention.
The engines were originally fitted with Giffard injectors - these proved unsatisfactory in service and were replaced by crosshead pumps.
This engine is the work of a prolific builder, responsible for many engines over the years - we've sold several of them in the past. We have some documentation with it, including past club boiler certification.
I love the notion of naming a class of engines "Problem" - it's the sort of thing that wouldn't get past the first marketing meeting these days.
