The original link I posted had about 600 pages on the Corporal. Towards the end of the second one they described the engine construction and development history and give a cross section diagram. BUT there were 3 engines mentioned. While they SAY that they never got the 3rd into production it's always possible that the lessons learned on #3 got used on later production versions. So, while I think the rocket here is a #2 engine with mild steel all through, it's possible that it has stainless or even something else in places. I really want to get it right as thr watchdogs are being very proper about how things are done and I want to be able to show that I know as much as possible about what they have. I already know far more than they do, but more is always useful.
