The detail and effort folk put into some of those scale engines is quite unreal. My cousin has a couple of them, he has even scratch built to scale tool kits for them, wrenches, bottle jacks the works, I don't know how he has the patience or imagination.
Took him 4 years That the second one I would not have the patience or the want to smell like a 1940 GWR carriage seat
All power to them though
I think it is the steam train people who count rivets @frank horton Have seen the cards on exhibits at the model engineers shows
