In the 1950's there was a comic called the Eagle, In this comic the centre pages always had cutaway drawing showing how things worked.
They covered trains, cars, planes cars along with other subjects.
Here I have collected most of the cutaways which Have assembled but I have some missing, I also have a few where I didn't know the dates or were wrongly dated so I have put them in the Misc section
